PROBLEM 20: State if the triangles in each pair are similar. If so, state how you know they are similar (SSS Sim, AA Sim, or SAS Sim.) and complete the similarity statement. (The problem to workout should have a triangle with both 86 degrees & 83 degrees in it.)

16) Find the missing length indicated by the ?, or solve for x. Find the coordinates of the vertices of each figure after the given transformation. 17) dilation of 2.5 about the origin E(-2, 0), F(2, 2), G(1, -1) A) E(-5, 0), F (5, 5), G(2.5, -2.5) B) E'(-3, 0), F(1, 2), G (0, -1) C) E'(-4, 0), F(4, 4), G (2, -2) D) E(-3, 0), F (3, 3), G(1.5, -1.5) Write a rule to describe each transformation. 18) E A) dilation of - about the origin B) dilation of 1.5 about the origin C) dilation of ~ about the origin D) reflection across y = 1 State if the triangles in each pair are similar. If so, state how you know they are similar (SSS Sim., AA Sim., or SAS Sim.), and complete the similarity statement. 19) 20) W 12 86 83 0 10 10 20 AWVU~ ATUV ~
