Parallel Lines and Transversals Practice

Corresponding angles are pairs of angles that are in the same position on two parallel lines cut by a transversal. For example, if two parallel lines are crossed by a transversal, angle 2 and angle 10 are corresponding angles.

$$\text{Angle 2 and Angle 10}$$ .

Alternate exterior angles are pairs of angles that lie outside the two parallel lines and on opposite sides of the transversal. For example, angle 3 and angle 13 are alternate exterior angles.

$$\text{Angle 3 and Angle 13}$$ .

Alternate interior angles are pairs of angles that lie between the two parallel lines and on opposite sides of the transversal. For example, angle 3 and angle 6 are alternate interior angles.

$$\text{Alternate interior angles}$$ .

Vertical angles are pairs of angles that are opposite each other when two lines intersect. They are always equal in measure.

$$\text{Vertical Angles}$$ .

Consecutive interior angles are pairs of angles that lie between the two parallel lines and on the same side of the transversal. They are supplementary, meaning they add up to 180 degrees.

$$\text{Consecutive interior angles are supplementary.}$$ .
