# Side Side Side Postulate

## Proving Congruent Triangles with SSS

The Side Side Side postulate states that if three sides of one triangle are congruent to three sides of another triangle, then these two triangles are congruent.
Example 1

Given:$$AB \cong BC, BD$$ is a median of side AC.
Prove: $$\triangle ABD \cong \triangle CBD$$
