6-8 part 1 Angles formed by Parallel Lines and a Transversal

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

What is the relationship between alternate interior angles?

Back

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

Front

Define consecutive interior angles.

Back

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

Front

What is the measure of angle 4 if angle 1 = 27°?

Back

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

Front

If angle P measures 60 degrees, what is the measure of angle C if they are alternate interior angles?

Back

Angle C = 60° (because alternate interior angles are equal).

Front

What is the sum of the measures of consecutive interior angles?

Back

The sum of the measures of consecutive interior angles is 180 degrees.

Front

Which angles are not congruent to angle 5?

Back

Angle 6 is not congruent to angle 5.

Front

If angle C = 116°, what is the measure of angle D if they are corresponding angles?

Back

Angle D = 116° (because corresponding angles are equal).

Front

What is the measure of angle 6 if angle 5 = 120°?

Back

Angle 6 = 120° (because they are alternate exterior angles).

Front

If angle 1 = 27°, what is the measure of angle 3?

Back

Angle 3 = 153° (because angle 1 and angle 3 are supplementary).
