# Geometry for Elementary School/The Side-Angle-Angle congruence theorem

In this chapter, we will discuss yet another congruence theorem, the Side-Angle-Angle congruence theorem, usually abbreviated as SAA(or AAS - Angle-Angle-Side , commonly used in India)

## The Angle-Side-Angle congruence theorem edit

Given two triangles and such that their sides are equal, hence:

- The angle equals .(they have the same angle )
- The angle equals .(they have the same angle )
- The side equals .(they have the same side )

Then the triangles are congruent and their other angles and sides are equal too.
