SideSideSide (SSSSimilarity):
If the lengths of all three of the corresponding sides of two triangles are multiples of each other (i.e., they are proportional), then the triangles are similar. 
Similar Triangles: Determine proportions comparing the side lengths of similar triangles.
Side Splitter: Find a relationship between sides in two triangles.
Altitude to the Hypotenuse: Investigate the relationship between sides of right triangles when an altitude is drawn to the hypotenuse of a right triangle.
