May 3, 2018 Homework * workbook, pg. 110 * Core Assessment #2 Friday, May 11 * Unit 8 Test Tuesday, May 15 (100 points) Warm-up Solve for x. Show work. 39/(x + 7) = 21/7 21(x + 7) = 39 * 7 21x + 147 = 273 21/21 * x = 126/21 x = 6 May 3, 2018 Using Similar Triangles 5.4 Similar figures have the same shape, but not necessarily the same size. May 3, 2018 A D ZA corresponds to angle D angle B corresponds to angle E angle C corresponds to F B C overline AB corresponds to overline DE overline BC corresponds to overline EF E F overline AC corresponds to overline DF Properties of Similar Figures 1. Corresponding angles of similar figures are congruent. angle A cong angle D, angle B cong angle E, angle C cong angle F 2. The ratios of the lengths of corresponding sides of similar figures are equal. (AB)/(DE) = (BC)/(EF) = (AC)/(DF) May 3, 2018 ABCD-WXYZ A B Y Z 5 3 2 X D C X W (wz)/(AD) -> (xy)/(Bx) -> x/5 = 3/3 3x= 3 x = 3 1/3 #what is the ratio of ABCD to wXY?? (Bc)/(xy) = 3/2 3 to 2 If FGHJKL, find: F 1. angle K 60 deg 2. KL 21in. L 60 deg G 21 in. H J K
