Question

two angles that are opposite each other when two lines intersect are called

angles that are on opposite sides of a transversal and between two parallel lines are called

angles that are on the same side of a transversal and in corresponding positions relative to two parallel lines are called

Explanation:

1. Recall the definition of vertical angles which are formed when two lines intersect and are opposite each other.
2. Recall the definition of alternate - interior angles which are on opposite sides of a transversal and between two parallel lines.
3. Recall the definition of corresponding angles which are on the same side of a transversal and in corresponding positions relative to two parallel lines.

Answer:

1. Vertical angles
2. Alternate - interior angles
3. Corresponding angles
