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: WebFor ABC shown above, ∠CAD is the exterior angle for ∠A and ∠B and ∠C are the two remote interior angles. We know that ∠CAB + ∠B + ∠C = 180°. Also, ∠CAB and ∠CAD form a straight angle, so ∠CAB + ∠CAD = 180°. Since both sums equal 180°: ∠CAB + ∠CAD = ∠CAB + ∠B + ∠C ∠CAD = ∠B + ∠C The same can be shown for any exterior angle of any triangle. duxbury youth lacrosse facebookWebThe figure below shows right triangle (ABC) with angle C being a right angle.
