# Congruence to Simple Geometrical Shapes

## About

The two figures which are same in shape and size are called congruent figures and the relation of two figures being congruent is called congruence.

The symbol to denote congruence is ≅.

## Congruent line segments

Two line segments are congruent if both have the same length.

## Congruent circles

Two circles are congruent if both of them have the same radii.

## Congruent triangles

Two triangles are congruent if both of them have the same length of sides.

Congruent rectangle

Two rectangles are congruent if both of them have the opposite sides are equal.

Thus, the method of comparing two figures is known as the method of superposition.
