what are polygons?

Introduction to what type of polygon are there :
In this section let me try to help you on what are polygons. The polygons are basically called as a plane figure and that is surrounded with closed path, collected of a fixed series in straight line segments with a nearer polygonal chain. The basic figure of the polygon are shown below . Let us examine on the topic called what types of polygon are there.

The Types of Polygon Diagrams are Follows :
The triangle is the basic method in polygons and it has three angles. This involves three sides and three vertices.

Square
The octagon

A polygon is a n sided two dimensional figure. Polygon with four sides is commonly known as quadrilateral. Quadrilaterals are square, rectangle, rhombus, paralleologram, kite and trapezoid. These shapes are generally known one. There are some more figures with four sides and those figures are irregular in shape. This could also help us on what is a prime factor. The geometric terms area, perimeter can be calculated for the figure which has 4 sides

super math world

In this lesson let me help you on super math world. We call this super math world just because with out math we may not be able to run our day today life.

Math plays an important role in our life. It helps us in making our day today activities easy with the help of calculation. Helps us realize where we stand in our business helps us improve that.

Every human in this world strive to learn math not just to get their job done in a perfect way but also helps them to analyze them self with this new world. This could also help us on magnification equation.

Note on isosceles triangle

Introduction:
In this article let us learn on isosceles triangle and right angle. A triangle should be the base shapes of geometry. Line segments are the polygon. Isosceles triangles are one type of triangles.
In this angle of right angle could be an angle that will divide the angle created by two halves of a straight line. More precisely, when a ray should place that means its endpoint is over a line. And adjacent angles are equal. These angles are known as right angles.

Isosceles Triangle:
Shape of Isosceles triangle:



This could also help us on reactivity series An isosceles triangle should have two equal sides. In the figure, two equal sides can contain length b. And also remaining side has length a.properties of angles should be equal to the two angles of triangle that are equal. This triangle has two equal sides and also two equal angles.

pre algebra homework help free


In this article let me help you on pre algebra homework help free

Free Pre Algebra Homework Help- Example Problems:

Consent to us observes some of the free pre algebra homework help problems.
Free pre algebra homework help- Example 1:
Solve the following algebraic equations
4x + 4 = 12
Solution:
First we have to add both sides -4 we get
4x+4-4 = 12-4. This could also help us on algebra 2 problems solved
In left hand side 2-2 is cancelling reaming we get
4x =-8
Divide both sides 4 we get
x = -2
Therefore the value of algebraic variables are x = -2

free algebra word problems

Introduction:

In this article let me help you on free algebra word problems. The first real course in mathematics is free algebra word. Depending on the principles of arithmetic that already have studied, free algebra word uses symbols to create generic solutions which work in various cases.

Free algebra word problem is a type of textbook word problem designed to help students apply abstract mathematical concepts to real-world situations.
Sample Problems:

Problem 1

ax ± b = c. All algebra problems are like the following one.

David spent 24 for shoes, this was 8 less than twice what she spent for a blouse. How much was the blouse?

Solution:

Every word problem has an unknown number. In this problem, unknown number is the price of the blouse. Constantly, let x represent the unknown number. That is, let the x value answer the question. This can also help us on free math tutoring online

Let x, how much he spent for the blouse. Here becomes the equation:

2x – 8 = 24

In the right side, the -8 will become +8.

2x = 24+8

x = 32/2

x = 16

The correct answer is x = 16.

Note on Mass Number

Introduction to the mass number:

Mass number is the total of the number of protons and the number of neutrons in an atom. The number of protons in an atom is atomic number. For example, a uranium atom that has 92 protons and a mass number of 238.

The Mass Number is Used to Calculate the Number Of

Atomic mass number is unique for an element or each isotope of an element. When we subtract the atomic mass number from the atomic number. We get the number of neutrons (N) in a nucleus: N=A−Z

Mass number can be used to calculate the number of neutrons. This can also help us on 5th grade math. If there is a reaction which forms isotopes of an element or a different element, the mass number of the resultant element can be calculated using the mass number of the initial element.

Volume of a Cube

Introduction to Volume of a Cube
A solid bounded by six square faces is called a cube.
PROPERTIES OF A CUBE
A cube is a 3 dimensional figure as it has three parameters namely length, width and height which are equal.
Edge: The intersection of two faces is a line known as edge. A cube has eight equal edges.
Vertex: The common point of two or more line segment is known as vertex. A cube has eight verticals of equal measure.
Volume: Volume is the measure of the space occupied by a 3 dimensional figure.
Unit of volume: Along with the magnitude of volume of a substance, we also require a unit to represent the volume.
The volume of the space region formed by a cube of edges 1 cm long is called a cubic centimeter and is written as 1 cu. cm or 1 cm. Similarly other units of volume can be metre or m, decampment etc. This could help us on decimal to fraction calculator


A cube of volume 1 cm is shown in the above figure. All the six edges of the cube are 1 cm each. Formula for volume of a cube: As all the sides are of equal length in a cube
Therefore volume, V = (length) = l
