Similar Triangles Geometry Ms. Hough 7-3

Angle Angle Similarity If two angles of one triangle are congruent to two angles of another triangle, then the two triangles are SIMILAR

Side Angle Side Similarity If two sides of two triangles of proportional, and the included angles are congruent, then the triangles are similar 75° ax bx 75° a b

Example 1 Find AE and DE C A x - 1 5 2 E B x + 5 D

Example 2 Determine whether the pair of triangles are similar. Justify your answer… 40° 20° 120° 120°
