Basic Geometry Concepts


Introduction to basic geometry concepts:

In basic geometry concepts, the geometry is all on the subject of shapes. Geometry was enormously major to prehistoric societies and was used for surveying, astronomy, direction-finding, and structure. Geometry is the study of angles and triangles, outer limits, area and quantity. It differs from algebra in that one develops a reasonable formation where mathematical relations are prove and functional.

Basic Geometry Terms:

Some of the basic terms in geometry are line, rays, angles, and plane.
Now we will discuss about basic concepts in geometry.
Line segment:

In these basic geometry concepts, a line segment is a straight line up segment which is division of the straight line among two points.
To organize a line section, one can inscribe AB.
The points on each surface of the line division are referred to as the finish points.
Ray:

In basic geometry concepts, a ray is the element of the line which consists of the arranged point and locates of all points on one elevation of the closing stages point.
Angle:

In basic geometry concepts, angle can be discrete as two rays or two line segments having a common finale position.
The endpoint becomes predictable as the vertex.
Angles come about while two rays accumulate or mix up at the matching endpoint.

Plane:

A plane is often instead of by a blackboard, communication board, a plane of a box or the peak of a table.
These 'plane' surfaces are damaged to connect any two or added points in a straight line.
A plane is a parallel frontage.

Types of Angles:

An angle is different as wherever two emission or two-line segment join mutually at a general endpoint is known as vertex.
In basic geometry concepts having some types of angles. these are,
Acute angle.
Right angle.
Obtuse angle.
Acute angle:

I like to share this Acute Angled Triangle with you all through my article.

An acute angle procedure a lesser of that 90°
Right Angle:

A right angle connections correctly 90°
Obtuse Angle:

An obtuse angle measures not required than 90° but less than 180°

Math Factors of 59


Introduction to math factors of 59:

Math factors are the numbers that we do product in show to get another number:

For example the number 6 has the factors 1, 2 and 3 as shown as follows,

6 =1 x 2 x 3

In this article we are going to learn how to factorize the numbers and all about the math factors of 59.


Math factors of 59:


In order to get the factors we have to divide with the numbers starting with the number 1.

Let us do the math factors of 59.

Step 1: Divide the number 59 by 1 we get 59.

Step 2: We can’t divide 59 further as it is a prime and it gives the result with the decimal

Point.

Step 3: Finally the factors of 59 are 1 and 59.

That is 59 = 1 x 59.

That is 59 = 59 x 1.

Note: prime number is a number which is divided by 1 and the number itself.


Example problems- Math factors of 59:


The following examples will make you clear about how to factorize the numbers in math.

Example 1:

Find the factors of 159

Solution:

Step 1: Divide the number 159 by 1 we get 159.

Step 2: As it is a odd number we cant divide it by 2 therefore it is better to go with 3

Step 3: Divide 159 by 3 :

159/3 = `(3*53)/3`

= 53 (where 3 cancels each other)

Step 4: As 53 includes in the above step it is also a factor of 159.

Finally the factors of 159 are 1, 3, 53 and 159.

That is 159 = 1 x 159;

That is 159 = 3 x 53;

That is 159 = 53 x3;

That is 159 = 159 x 1.

Example 2:

Find the factors of 259

Solution:

Step 1: Divide the number 259 by 1 we get 259.

Step 2: As it is a odd number we cant divide it by 2 therefore it is better to go with 3

Step 3: Dividing by 3 is also not possible so Divide 159 by 7 :

259/7 = `(7*37)/7`

= 37 (where 7 cancels each other)

Step 4: As 37 includes in the above step it is also a factor of 259.

Finally the factors of 259 are 1, 7, 37 and 259.

That is 259 = 1 x 259;

That is 259 = 7 x 37;

That is 259 = 37 x 7;

That is 259 = 259 x 1.

Example 3:

Find the factors of 359

Solution:

Step 1: Divide the number 359 by 1 we get 359.

Step 2: We can’t divide 359 further as it is a prime and it gives the result with the decimal

Point.

Step 3: Finally the factors of 359 are 1 and 359.

That is 359 = 1 x 359.

That is 359 = 359 x 1.

Basic Notes on Algebra


Introduction to basic notes on algebra:

Algebra is defined as the major part of mathematics which deals with the study of laws of the operations and those concepts which involves various polynomials, algebraic structures and the equations. There are various kinds of algebra which includes elementary algebra, abstract algebra, etc.

In this article we are going to see about the basic notes of algebra which includes various laws and some example problems.

Basic notes on the laws of algebra:

laws of algebra:

There are various laws that are used in algebra for solving the equations and various algebraic structures.

The first basic notes on algebra are addition which involves the commutative law.

It states that a + b = b + a

Example:  5+6 = 6 + 5

11 = 11

The commutative law can also be applied for multiplication.

The basic law for multiplication is given by

a * b = b *a

Example:    5* 6 = 6* 5

30 = 30

We can also use the associative law for both the addition and the multiplication.

The basic notes for the associative law in algebra for addition is given by

(a + b) + c = a+ (b + c)

Example: (1+2) + 3 = 1 + (2+3)

3 + 3 = 1 + 5

6 = 6

The associative law for multiplication is given by

(a * b) * c = a*(b * c)


Example: (1*2) * 3 = 1* (2*3)

2 * 3 = 1 * 6

6 = 6

The next important basic notes of algebra include the distributive law.

(a * b) + c = (a*b) + (a * c)

Example: (1 * 2) + 3 = (1 *2) + (1 * 3)

2 + 3 = 2 + 3

5 = 5

Understanding Quadratic Formula Problems is always challenging for me but thanks to all math help websites to help me out.

Notes on basic rules of algebra:

The additive inverse of a is given by –a for any constant or a variable.

Example :a + (-a) = 0 and 5 + (-5) = 0

The multiplicative inverse of a is 1/a for any constant or a variable.

Example: a * 1/a = 1 and 5 * 1/5 = 1

In case of addition the identity element is zero for any constant or variable.

Example: a + 0 = a and 5 + 0 = 5

In case of multiplication the identity element is one for any constant or variable.

Example: a * 1 = 1 and 5 * 1 = 5.

Area Math 4th Grade


Introduction to 4th grade math area:

Area is a quantity expressing the two-dimensional size of a defined part of a surface, typically a region bounded by a closed curve. The surface area of a 3-dimensional solid is the total area of the exposed surface, such as the sum of the areas of the exposed sides of a polyhedron. Area is an important invariant in the differential geometry of surfaces. In this article we shall discuss about 4th grade math area problem. (Source: Wikipedia)

4th grade math area example problem

Here we are going to discuss some 4th grade math area problems with detailed solutions.

Example 1:

Find the area of the rectangle, the rectangle base value 23m and height of rectangle is 10 m.

Solution:

Let base b = 23 and rectangle height h = 10.

Then the area of the rectangle formula = b × h

The area of the rectangle = 23 × 10

= 230 sq. meters.

Therefore the area of rectangle = 230 sq. meters.

Example 2:

Find the area of the circle, the circle radius value 12.

Solution:

Area of the circle formula = pi r2

Pi = 22/7 or 3.14

The area of the circle = 22/7× 12x12

= 452

Answer:

Therefore the area of circle = 452

Example 3:

Find the area of the square; the square one side of length value is 22units.

Solution:

Formula for finding area of square = a2 of (Side) 2

The side value of the area = 22

Therefore (22) 2

That is 22 * 22 = 484

Area of the square = 484units.

Example 4:

Find the area of triangle, the triangle base value=20cm and the height of the triangle = 12cm

Solution:

Area of the triangle formula = `1/2` b x h

Height of the triangle = 12

Base of the triangle = 20

Therefore area of triangle = `1/2` x 20 x 12

The area of triangle = 120cm

Example 5:

Find the area of the rectangle, the rectangle base value 22m and height of rectangle is 15 m.

Solution:

Let base b = 22 and rectangle height h = 15.

Then the area of the rectangle formula = b × h

The area of the rectangle = 22 × 15

= 330 sq. meters.

Therefore the area of rectangle = 330 sq. meters.

Understanding right triangle trigonometry is always challenging for me but thanks to all math help websites to help me out.

Practice Test for Basic Math


Introduction to mathematics:

Mathematics is the study of quantity, structure, space, and change. Mathematicians seek out patterns, formulate new conjectures, and establish truth by rigorous deduction from appropriately chosen axioms and definitions. There is debate over whether mathematical objects such as numbers and points exist naturally or are human creations. (Source: Wikipedia)

Basic Algebra Calculations


Introduction to basic algebra calculations:

Basic algebra is the branch of mathematics concerning the study of the rules of operations and relations, and the constructions and concepts arising from them, including terms, polynomials, equations and algebraic structures. The part of basic algebra calculations called elementary algebra calculations is often part of the curriculum in secondary education and introduces the concept of variables representing numbers. The variables are manipulated using the rules of operations that apply to numbers, such as addition. (Source: Wikipedia).

Examples for basic algebra calculations:

Example 1 for basic algebra calculations:

Find the value for x in (x+2) +(x-22) +(x+45) =0.

Solution:

The given expression is(x+2) +(x-22) +(x+45) =0.

In this above expression first add the constants separately and then add the variable x.

(x+2) +(x-22) +(x+45) = (x+ x+ x) + (2-22+45)

(x+ x+ x) + (2-22+45) =3x+25

3x+ 25=0

3x =-25

x=-25/3

The value for x in (x+2) +(x-22) +(x+45) =0 is -25/3.

Example 2 for basic algebra calculations:

Find the value for the quadratic equation x ^2+6x +8=0.

Solution:

The given quadratic equation is x ^2+6x +8=0.

We have to find the roots for the above quadratic equation.

This can be solved by the factoring by middle term.

A=co-efficient 0f x ^2=1

B= co- efficient of x=6

C= constant=8

We split the 6 as (2+4), and then only we get 2 x4 =8.

x ^2+6x +8= x ^2+2x+4x +8

Take x as common in first two terms and 4 as common in next two terms.

x ^2+6x +8= x(x+2)+4(x+2)

x ^2+6x +8= (x+4) (x+2)

(x+4) (x+2) =0

x+4 =0 and x+2 =0

In the equation x+4 =0, subtract 4 on both sides.

x+4 =0

x+4-4 =0-4

x=-4

In the equation x+2 =0, subtract 2 on both sides.

x+2 =0

x+2-2 =0-2

x=-2

The roots for the equation x ^2+6x +8=0 is x=-2,-4.
