An angle with a measure between 90  and 180  ___C____ 6. angle bisector F. A figure formed by two rays that have the same endpoint. ____I___ 7. vertical angles G. Angles that have a common vertex and side, but share no interior points ____E___ 8. obtuse angle H. A pair of angles that add up to 180  __G_____ 9. adjacent angles I. Two non-adjacent angles formed by two intersecting lines.

10.If A is between B and C, AB = 1.3 and AC = 15.6, what is BC? = If M is between J and K, JM = 2x - 14 and MK = x – 4 and JK = 24, then what is the value of x and JM? 2x – 14 + x – 4 = 24 x = 14 and JM = M is the midpoint of AB. If AM = 2x + 6 and MB = 14, find x and AB. Hint: Draw a diagram 2x + 6 = 14 x = 4 AB = 28

10x x + 2 = 84 x = 4 10x – 103 = 59

Distance = 10Midpoint = (0, 3) <1 and < 4 are also complementary 7x – x + 1 = 180 x = 16 They are supplementary
