📚 Topic Summary
The Side-Side-Side (SSS) Congruence Theorem states that if all three sides of one triangle are congruent (equal in length) to the corresponding three sides of another triangle, then the two triangles are congruent. In simpler terms, if two triangles have the same side lengths, they are exactly the same shape and size!
This theorem is a fundamental concept in geometry and allows us to prove triangle congruence without needing to know anything about the angles.
