1. Given ZCDE shown below, construct its image, ZC'D'E' after a dilation using F as the center and a scale factor of 2. Leave all construction marks. C 2. Using your protractor, find the measure of both of the following angles: (a) mZCDE = F . (b) mZC'D'E'= E 3. Why isn't the measure of ZC'D'E' twice the measure of ZCDE in #2 above? PROBLEM SOLVING 4. If rectangle RSTV is dilated with a scale factor of - with a center at R then which of the following is the value of mZS'T'U'? (1) 45 (3) 120" (2) 90 (4) 180" 5. In rhombus ABCD shown, mZA =140" and diagonal BD has been drawn. 140 If side BC is dilated with D as the center and a using a scale factor of - then which of the following would be the measure of ZDB'C!? (1) 10 (3) 40 C (2) 20" (4) 70'6. In isosceles triangle ABC it is known that AB = AC. If MBC is dilated using B as the center point, then which of the following could he an incorrect statement? Draw a good diagram! (1} (BAcgzA'C' (2} AABCEAAT? (3} zc'raamac (4} ZBCA ; LA'BC' 7. In the following diagram, D and Elie on sides E and TC such that nsc as marked. . A It is known that AD = [8 and 93:12. (a} Give a dilation that would map E onto E. State both the center of the dilation and the scaling factor. B C (b) If RC = [5 and AC = 20 , then nd the perimeter of MDE . Show how you an-ived at your answer. 8. Given two concentric circles [circles that have the same center point], with the inner circle having a radius of f] and the outer one having a radius of r] as shown. give a dilation that would map the inner circle onto the outer circle. Specify both the center of dilation and the scale factor. REASDNING 9. Explain why two perpendicular lines will remain perpendicular if they are both dilated by the same factor and using the same center
