Ways to Prove Triangles SIMILAR
SideAngleSide Similarity (SAS~) Theorem If an angle of one triangle is congruent to an angle of a second triangle, and the sides including the two angles are proportional, then the triangles are similar.
SideSideSide Similarity (SSS~) Theorem If the corresponding sides of two triangles are proportional, then the triangles are similar.

Jenny places a mirror 24 ft from the base of a flagpole. When she stands 3 ft from the mirror, she can see the top of the flagpole reflected in it. If her eyes are 5 ft above the ground, how tall is the flagpole?
When a 6 ft tall man casts a shadow 18 ft long, a nearby tree casts a shadow 93 ft long. How tall is the tree?
