Proving Congruence of Two Triangles by SSS - Congruent Triangles

The video tutorial explains how to prove that two triangles, LMN and LPN, are congruent using a two-column proof method. It discusses the given information, such as congruent lines and angles, and explores methods like Side-Side-Side (SSS) and Side-Angle-Side (SAS) to determine congruence. The concept of included angles is also covered, leading to the conclusion that the triangles are congruent by SSS.
