37. Sample answer: 38. m / AKB 1 m / BKC 1 m / CKD 5 20 1 25 1 45 or 90, so / AKD is a right angle and A w K w ' K w D w . m / DKE 1 m / EKF 5 60 1 30 or 90, so / DKF is a right angle and K w D w ' K w F w . m / EKF 1 m / FKG 5 30 1 60 or 90, so / EKG is a right angle and K w E w ' K w G w . 39. Because / WUT and / TUV are supplementary, let m / WUT 5 x and m / TUV 5 180 2 x .A bisector creates measures that are half of the original angle, so m / YUT 5 } 1 2 } m / WUT or } 2 x } and m / TUZ 5 } 1 2 } m / TUV or } 180 2 2 x } . Then m / YUZ 5 m / YUT 1 m / TUZ or } 2 x } 1 } 180 2 2 x } . This sum simplifies to } 18 2 0 } or 90. Because m / YUZ 5 90, Y w U w ' U w Z w . 40. Sample answer: The types of angles formed depends on how the streets intersect. There may be as few as two angles or many more if there are more than two lines intersecting. Answers should include the following. • linear pairs, vertical angles, adjacent angles • See students’ work. 41.
