# 6.3 proving triangles similar answers

• Answer. For any problem involving a 30°-60°-90° triangle, the student should not use a table. The student should sketch the triangle and place the ratio numbers. Since the cosine is the ratio of the adjacent side to the hypotenuse, you can see that cos 60° = ½. Example 2. Evaluate sin 30°. Answer.

• To prove that OP ≅ OQ is enough to prove that OPM ≅ OQM. 1) ∠QOM ≅ ∠POM (OL is a bisector), 2) ∠OQM ≅ ∠OPM = 90° 3) OM is a shared side. Therefore, the both triangles OPM and OQM are congruent by Angle-Angle-Side. Problem 4 Prove that if CP is an altitude and a bisector then the triangle ABC is isosceles.
• There are several ways to prove certain triangles are similar. The following postulate, as well as the SSS and SAS Similarity Theorems, will be used in proofs just as SSS, SAS, ASA, HL, and AAS were used to prove triangles congruent.
