5 Answer Key cm in or about in Performance Assessment 1. Perpendicular Bisector Theorem. B is the midpoint of AC since BE is a midsegment ; Def. of perpendicular bisector 4. BDC, DBE, EDB, ABE, A. AE AB; AEB 90, ABE 4, and, if two angles in a triangle are not congruent, then the longer side is opposite the larger angle. 6. The triangles are not congruent. The reasoning in the answer for question can be used to show that AB AE and AB EB and likewise that DC BC. But since AB BC, it follows that DC is longer than each side of ABE. Therefore ABE cannot be congruent to CDB. 7. a. 14 b. 14, or about 19.8 c. 8 d. 8, or about C 0. H. F 1. C 3. D. G 4. H 3. A. A 4. H 6. G. B 7. A 6. F 8. J 7. D 9. D 8. H 10. G 9. B 11. C 30. J 1.
