Side-Angle-Side Similarity Theorem

Rule

Side-Angle-Side Similarity Theorem

If two triangles contain one congruent angle and the two adjacent sides of this angle are proportional to their respective counterparts, then the triangles are similar.

Since the triangles are similar, the remaining corresponding angles are also congruent and the third side in the triangles is also proportional.
