Understanding Triangle Congruence

The video tutorial explains a geometric proof involving a quadrilateral ABCD with a line BD. It demonstrates how to prove two triangles are congruent using given congruent segments and the reflexive property. The proof is completed by applying the side-side-side postulate, showing that all sides and corresponding angles of the triangles are congruent.
