WebSep 4, 2024 · Answer: A B C ∼ D E C. Example 4.2. 3 Determine which triangles are similar and write a similarity statement: Solution ∠ A = ∠ A identity. ∠ A C B = ∠ A D C = 90 ∘. Therefore Also ∠ B = ∠ B, identity, ∠ B D C = ∠ B C A = 90 ∘. Therefore Answer: A B C ∼ A C D ∼ C B D. Similar triangIes are important because of the following theorem: WebThat is, that a=A, b=B, and c=C. There are no similarity criteria for other polygons that use only angles, because polygons with more than three sides may have all their angles equal, but still not be similar. Consider, for example, a 2x1 rectangle and a square. Both have four 90º angles, but they aren't similar.
