5. Quiz 2 In the figure, are the lines parallel, intersecting, or skew? 5. and _________________________ 6. and _________________________ 7. and _________________________

6. Quiz 3 In Exercise 1, use the figure and find LM. 1. and X = ________ LM = _______ 2. Use the figure to find each of the following. a. x _________ b. MR ________ c. RP ________

7. Quiz 3 Name an angle or angles in the diagram described by each of the following. 3. supplementary to ____________________ 4. complementary to ___________________ 5. congruent to ___________________ 6. a pair of vertical angles____________________

8. Biconditionals Consider the true conditional statement. Write its converse. If the converse is also true, combine the statements as a biconditional.  If three points are collinear, then they lie on the same line.

9. Angle Measurements 1. If C is in the interior of < ABD and m<ABC = 2x - 1, m<CBD = 3x + 4, and m<ABD = 48, find x and the measure of all the angles. (Draw a picture, label and solve) 2. m<BOX = 2x – 7, m<XOY = 3x + 2. Find x. X Y OB
