15. GM = WH , MA1AG , MA s HO , HOI WO \A = ZO, MA = HO , GA = WO

IV. Given that AHIT = ATOP, write an equation and solve for x in each of the following. SHOWYOUR WORK!!

17.HT = 2x + 10, TP = 4x + 6, TO = 6x - 6

18.IT = 4x + 20, OT = 6x, IH = 2x + 44

VI. Always (A), Sometimes (S) or Never (N):23. -rT An equiangular triangle is isosceles, equilateral and acute.24. S A scalene triangle is a right triangle.

-^25. /*- The sum of the measures of the exterior angles of a triangle is 360 degrees.26. f\n equilateral triangle is isosceles.27. ]Kj An isosceles triangle is scalene.28. An equilateral triangle is a right triangle.29. CPCTC is used after triangles are congruent30. A CPCTC stands for Corresponding parts of congruent triangles are corresponding

VII. Free Response31. Find the value(s) of x
