Congruence of Triangles

Congruence of Triangles refers to the concept that two triangles are said to be congruent if they have exactly the same shape and size. In other words, if two triangles are congruent, all their corresponding sides and angles are equal.

There are various ways to prove the congruence of triangles. Some of the most commonly used methods are:

1. Side-Side-Side (SSS) Congruence: If the three sides of one triangle are equal to the corresponding three sides of another triangle, then the triangles are congruent.

2. Side-Angle-Side (SAS) Congruence: If two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, then the triangles are congruent.

3. Angle-Side-Angle (ASA) Congruence: If two angles and the included side of one triangle are equal to two angles and the included side of another triangle, then the triangles are congruent.

4. Angle-Angle-Side (AAS) Congruence: If two angles and a non-included side of one triangle are equal to two angles and the corresponding non-included side of another triangle, then the triangles are congruent.
