Similarity Shortcut Triangle Similarity

There are four triangle congruence shortcuts: SSS, SAS, ASA, and AAS. We have triangle similarity if (1) two pairs of angles are congruent (AA) (2) two pairs of sides are proportional and the included angles are congruent (SAS), or (3) if three pairs of sides are proportional (SSS). Notice that AAA, AAS, and ASA are not listed -- to include them would be redundant since they all have two congruent angles.
