Below are sample questions representative of the exercises included on this worksheet and related 8.142 Identifying and Using Angle Pairs in Parallel Lines skill assessments:

Problem 1Difficulty: Hard
Lines m and n are parallel and cut by transversal p. At the top intersection, angles J, K, L, M are labeled clockwise starting with the upper-left angle. At the bottom intersection, angles N, O, P, Q are labeled the same way. After solving for x from angle K = 6x - 26 and angle Q = 4x + 4, find the sum of the four angles that are supplementary to angle K.
Solution & Explanation:First solve for x. Angle K measures 64 degrees, so each supplementary angle measures 116 degrees. There are four such angles, so the total is 464 degrees.
Problem 2Difficulty: Hard
Lines y and z are parallel and cut by transversal k. The upper intersection labels are P, Q, R, S, moving clockwise from upper-left. The lower intersection labels are T, U, V, W, also moving clockwise from upper-left. Use angle P = 5x + 59 and angle W = 7x + 13 to find the sum of angle P and angle V.
Solution & Explanation:First solve for x using the fact that angle P and angle W are same-side exterior angles. Then find angle P = 104 degrees and angle V = 104 degrees, so their sum is 208 degrees.
Problem 3Difficulty: Hard
Choose the relationship between the lower-left angle at the top intersection and the upper-right angle at the bottom intersection.
Aalternate interior angles
Bvertical angles
Csame-side exterior angles
Dsame-side interior angles
Solution & Explanation:These positions create alternate interior angles.
