Parallel Lines and Transversals

Front

What are Corresponding Angles?

Back

Corresponding angles are pairs of angles that are in similar positions at each intersection where a straight line crosses two others. They are equal in measure.

Front

What are Alternate Interior Angles?

Back

Alternate interior angles are pairs of angles that lie between two lines and on opposite sides of a transversal. They are equal when the lines are parallel.

Front

What are Consecutive Interior Angles?

Back

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

Front

What are Alternate Exterior Angles?

Back

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

Front

If Angle R and Angle C are Corresponding Angles, what can be said about their measures?

Back

If Angle R and Angle C are corresponding angles, then their measures are equal.

Front

If Angle S and Angle A are Alternate Exterior Angles, what can be said about their measures?

Back

If Angle S and Angle A are alternate exterior angles, then their measures are equal.

Front

Solve for y if 2y + 10 = 80.

Back

y = 35.

Front

If Angle 1 = 27°, what is the measure of Angle 4 if they are corresponding angles?

Back

Angle 4 = 27°.

Front

What is the measure of ∠3 if it is a Consecutive Interior Angle to a 55° angle?

Back

∠3 = 125°.

Front

What is the relationship between Alternate Interior Angles when two lines are parallel?

Back

Alternate interior angles are equal when the two lines are parallel.
