Question

Explain the concept of congruence of figures with the help of certain examples.

Answer 1

Congruent objects or figures are exact copies of each other or we can say mirror images of each other. The relation of two objects being congruent is called congruence.

Consider Ball A and Ball B. These two balls are congruent.


Now consider the two stars below. Star A and Star B are exactly the same in size, colour and shape. These are congruent stars.


Let us look at the triangles below, Here we have triangle PQR and triangle DEF.
These two triangles have corresponding angles equal and corresponding sides equal. Thus these triangles are congruent to each other.
