Theorem 8.3: 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.

Unit 4 Similarity. Unit 5 Right triangles & trigonometry. Unit 6 Analytic geometry. Unit 7 Conic sections. Unit 8 Circles. The SSS similarity criterion says that two triangles are similar if their three corresponding side lengths are in the same ratio. That is, if one triangle has side lengths a, b, c, and the other has side lengths A, B, C, then the triangles are similar if A/a=B/b=C/c. These three ratios are all equal to some constant, called the scale factor. Section 6.1: Similar Figures Section 6.2: Prove Triangles Similar Section 6.3: Side Splitter Thoerem Unit 6 Review Mr. Riggs MathematicsExample: these two triangles are similar: If two of their angles are equal, then the third angle must also be equal, because angles of a triangle always add to make 180°. In this case the missing angle is 180° − (72° + 35°) = 73°. So AA could also be called AAA (because when two angles are equal, all three angles must be equal).3.2K plays. 4th - 8th. 20 Qs.
