Geometry Ratios Triangles

What is the Angle-Angle (AA) Similarity Theorem?

• If two angles of one triangle are congruent to two angles of another triangle, then the two triangles are similar

• If the corresponding side lengths of two triangles are proportional, then the triangles are similar

• If an angle of one triangle is congruent to an angle of a second triangle, then the triangles are similar

• If two triangles have the same area, they are similar
