Side Side Side PostulateProving 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: $$ \triangle ABD \cong \triangle CBD $$
