ABSTRACT
Similarity tests for triangles: 1. If all three pairs of corresponding sides in a pair of triangles are in proportion, then the
triangles are similar. 2. If two pairs of corresponding angles in a pair of triangles are congruent, then the triangles
are similar. 3. If two pairs of corresponding sides in a pair of triangles are in proportion and the
included angles are congruent, then the triangles are similar.
