11D Angles formed by Parallel Lines and a Transversal

Front

What are alternate exterior angles?

Back

Alternate exterior angles are pairs of angles that lie outside the two parallel lines and on opposite sides of the transversal. They are equal in measure.

Front

What are corresponding angles?

Back

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

Front

If angle 1 = 27°, what is the measure of angle 4?

Back

Angle 4 = 27° (because they are corresponding angles).

Front

What is the relationship between alternate interior angles?

Back

Alternate interior angles are equal when two parallel lines are cut by a transversal.

Front

If two parallel lines are cut by a transversal, what can be said about the sum of the interior angles on the same side of the transversal?

Back

The sum of the interior angles on the same side of the transversal is 180°.

Front

What are consecutive interior angles?

Back

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

Front

If angle 5 = 90°, what is the measure of angle 6?

Back

Angle 6 = 90° (because they are vertical angles and are equal).

Front

What is the measure of angle 8 if angle 7 = 116°?

Back

Angle 8 = 116° (because they are alternate interior angles and are equal).

Front

Which angles are NOT congruent to angle 5 if angle 5 = 63°?

Back

Angle 6 is NOT congruent to angle 5.

Front

What is the definition of a transversal?

Back

A transversal is a line that intersects two or more lines at different points.
