Showing two triangles are similar when they overlay each other using SAS

The video tutorial explains how to determine the similarity of triangles using criteria such as angle-angle and side-side-side. It guides students through identifying overlapping triangles and calculating side lengths. The tutorial also covers proving congruency by comparing angles and ratios, emphasizing the importance of finding common angles and equivalent side ratios to establish similarity.

What method was suggested to prove the triangles are similar when the third side is not known?

How can the ratios of the sides be used to prove triangle similarity?
