Geometry Honors Ms Curry Name: _______________________ Date : _____________________ Unit 3 Test Review 9. a. b. If 1 7 , what theorem or postulate allows you to conclude that a b ? 10. The measures of the acute exterior angles a right triangle are 3x + 25 and 5x + 5. Find the measures of the angles of the triangle. (Hint – draw a picture!) 11. The ratio of measures of the angles of a triangle is 2:4:5. Find the angles of the triangle, and classify the triangle. 12. Name the polygon with an interior angle sum of 1080 . 13. Find each exterior angle of a regular 15-gon. 14. Each interior angles of regular polygon is 36 . How many sides does the polygon have? 15. Solve for x. a. 16. b. 23. Use the following diagram for proofs #24 and #25. Do not use the information from #24 for #25. They are separate proofs. 24. Given: AC DE Prove: m1 m2 m5 25. Given: 3 is Supplementary to 5 .
