Angles Formed by a Transversal

Front

What is a transversal?

Back

A transversal is a line that passes through two or more parallel lines, creating angles.

Front

Which angles are formed when a transversal intersects two parallel lines?

Back

Corresponding angles, alternate interior angles, alternate exterior angles, and consecutive interior angles.

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in the same position on two different parallel lines cut by a transversal.

Front

What are alternate interior angles?

Back

Alternate interior angles are pairs of angles that lie between the two parallel lines but on opposite sides of the transversal.

Front

What are alternate exterior angles?

Back

Alternate exterior angles are pairs of angles that lie outside the two parallel lines but on opposite sides of the transversal.

Front

What are consecutive interior angles?

Back

Consecutive interior angles are pairs of angles that lie between the two parallel lines on the same side of the transversal.

Front

If angle 1 = 27°, what is the measure of angle 5 if they are corresponding angles?

Back

Angle 5 = 27° (corresponding angles are congruent).

Front

If angle 1 = 27°, what is the measure of angle 4 if they are alternate interior angles?

Back

Angle 4 = 27° (alternate interior angles are congruent).

Front

If angle 3 = 110°, what is the measure of angle 6 if they are alternate exterior angles?

Back

Angle 6 = 110° (alternate exterior angles are congruent).

Front

If angle 2 = 80°, what is the measure of angle 7 if they are consecutive interior angles?

Back

Angle 7 = 100° (consecutive interior angles are supplementary).
