Question

8 | lesson: transversals and parallel lines: solving unknown a... which angle type is formed outside the parallel lines on opposite sides of the transversal? a. corresponding angles b. consecutive interior angles c. alternate exterior angles d. alternate interior angles what is the measure of each angle in a pair of vertical angles if one of them is 45 degrees? a. 135 degrees b. 90 degrees c. 180 degrees d. 45 degrees

Explanation:

1. Alternate exterior angles are formed outside the parallel lines on opposite sides of the transversal. Corresponding angles are in the same - relative position, consecutive interior angles are inside the parallel lines on the same - side of the transversal, and alternate interior angles are inside the parallel lines on opposite sides of the transversal.
2. Vertical angles are congruent. So if one of the vertical angles is 45 degrees, the other one has the same measure.

Answer:

1. c. Alternate exterior angles
2. d. 45 degrees
