TRIANGLE to ICOSAGON -All about Polygons(Let's plunge in #7)

-

 Hi all, hope you are doing well.

Mathematics is an interesting area,

It's fun to dive into it.

Let's start today's topic. POLYGONS.


What is a shape?

SHAPE is the outline of something.

Then what are 2D shapes?

2D shapes are shapes with two dimensions such as width and height.


Do you heard about Polygons?        
                                                                          
Polygons are 2 dimensional closed shapes. 
They are joining with 3 or more line segment each other.

Then what is regular polygon and irregular polygon?                                          
polygon with all the sides are equal and all interior angles are equal is regular polygon.
examples are    square , equilateral triangle.
Polygon with different interior angles is called irregular polygon.
examples are  rectangle , trapezoid

An n-gon is a polygon with n sides.
for example, a triangle ia a 3-gon.
A simple polygon is one which does not intersect each other.

now, let's study the names of polygons

 Polygon with 3 sides is known as a TRIANGLE 
             Polygon with 4 sides is known as a QUATRILATERAL  
  Polygon with 5 sides is known as a PENTAGON
Polygon with 6 sides is known as a HEXAGON
  Polygon with 7 sides is known as a HEPTAGON
Polygon with 8 sides is known as a OCTAGON
 Polygon with 9 sides is known as a NANOGON
  Polygon with 10 sides is known as a DECAGON
          Polygon with 11 sides is known as a HENDECAGON 
        Polygon with 12 sides is known as a DODECAGON
         Polygon with 13 sides is known as a TRIDECAGON 
               Polygon with 14 sides is known as a TETRADECAGON 
               Polygon with 15 sides is known as a PENTADECAGON 
              Polygon with 16 sides is known as a HEXADECAGON  
                 Polygon with 17 sides is known as a HEPTADECAGON   
              Polygon with 18 sides is known as a OCTADECAGON  
                 Polygon with 19 sides is known as a ENNEADECAGON   
     Polygon with 20 sides is known as a ICOSAGON  

Woah! This should be easy enough!
Bye, and stay tuned for the next blog! :-)

  Hi all, hope you are doing well. Mathematics is an interesting area, It's fun to dive into it. Let's start today's topic. SHAPES What is a shape? SHAPE is the outline of something. The shapes are closed by outline made by points, line segments or curved lines. we can see different objects in our daily life are in different shapes such as birthday cap, ruler, photo frame, wall clock etc In this figure we can see basic shapes such as circle, square, triangle, Rectangle etc. A closed figure or closed shape can be defined as any geometric shape which starts and ends at the same point to form a boundary by line segments or by curves.  Shapes shown in the above picture are closed figures. Open figures are incomplete shapes.  An open figure’s starting and endpoints are different. Classification of shapes Depend upon its  regularity or uniformity shapes are divided into two 1. Regular shapes  2.Irregular shapes A  regular shape  is usually symmetrical . E...

 How many types of numbers do you know? You may know these number systems: i) Natural Numbers     ii) Whole Numbers iii) Integers iv) Negative Natural Numbers v) Rational Numbers etcetera But what are Ordinal numbers? This is our question for today! 😊     A number defining the position of something in a series are known as "Ordinal Numbers". These are some ordinal numbers for your better understanding. Woah! This should be easy enough! Bye, and stay tuned for the next blog!  :-)
