Answer:
1. Vertical Angles
2. Corresponding Angles
3. Alternate Interior Angles
4. Consecutive Interior Angles
5. ?
Explanation:
1. Pairs of opposite angles made by intersecting lines are called vertical angles and they are congruent.
2. Angles at the same relative position at each intersection of a transversal are called corresponding angles and are congruent.
3. Angles that are located inside the parallel lines of a transversal, but on opposite sides are called alternate interior angles and are congruent.
4. Angles that are located inside the parallel lines of a transversal but on the same side are called consecutive interior angles and they are supplementary.
5. Unfortunately, I am uncertain about the answer to this question.
