7.6 SSS Similarity

Here you’ll learn how to decide whether or not two triangles are similar using SSS Similarity.

What if you were given a pair of triangles and the side lengths for all three of their sides? How could you use this
information to determine if the two triangles are similar? After completing this Concept, you’ll be able to use the
SSS Similarity Theorem to decide if two triangles are similar.
