◆Definition of a polygon:-  A polygon is any 2-dimensional shape formed with straight lines, such that triangles quadrilaterals Pentagons and hexagons etc. 



◆Definition of A Triangle :-  A three sided polygon is called triangle.  
          


◆Definition of A Scalene Triangle :- A triangle having three unequal sides is called scalene triangle.

◆Definition of A Isosceles Triangle:- A triangle having any two sides equal is called Isosceles triangle.

◆Definition of A Equilateral Triangle :- A triangle having all sides equal is called equilateral triangle.


◆Definition of A Acute Angled Triangle:- A triangle having all the three acute angles is acute angle is called acute angled triangle.


◆Definition of A Obtuse angled triangle :- A triangle having any one Obtuse angle is called obtuse angled triangle. 

◆Definition of A Right angled triangle :- A triangle having one angle as right angle is called right angled triangle. 


◆Perimeter of a Triangle :- The sum of all the three sides of a triangle is called it's perimeter.


◆Median of a Triangle :- The line joining the vertex to the mid point of opposite side of a triangle is called it median. 


◆Altitude of a triangle :- The perpendicular drawn from vertex to the opposite side of a triangle is called it's altitude. 


◆Bisector of Angle of a triangle:- The line bisecting the vertex angle of triangle is called bisector of angle of a triangle. 



◆Equiangular Triangle :- If corresponding angles of two triangles are same , then they are called equiangular triangles. 

◆Similar shapes :-  Figures having same shapes but different size , are called similar shapes.


◆Similar polygon:-  Two polygon are similar , if their corresponding angles are equal and their corresponding sides are in the same ratio.(i.e. proportion) 


◆Note:- two congruent figures are also similar but the converse is not true i.e. similar figures are not always congruent.
