A triangle have three edges and three vertices. A triangle is a basic shape in geometry.
In this chapter we will cover the following topics related to triangle.
-Similar figures
A similar figures have a same shape but a similar figures not have a same size. In geometry a two circle are similar, two squares are similar etc. 
-Similarity of triangles
A similar triangle have two triangles are said to be similar if their corresponding angles are equal and their corresponding sides are proportional.
-Criteria for similarity of triangles
-Area of similar triangles
-Pythagoras
In a right triangle the square of the hypotenuse is equal to the sum of the square of the other two side.
