Parallel Line Angles

Front

What are Same Side Interior Angles?

Back

Same Side Interior Angles are pairs of angles that lie on the same side of the transversal and between the two parallel lines. They are supplementary, meaning their measures add up to 180 degrees.

Front

What are Alternate Interior Angles?

Back

Alternate Interior Angles are pairs of angles that lie on opposite sides of the transversal and between the two parallel lines. They are equal in measure when the lines are parallel.

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. They are equal in measure.

Front

What are Alternate Exterior Angles?

Back

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

Front

If two parallel lines are cut by a transversal, what can be said about the angles formed?

Back

The angles formed will have specific relationships: corresponding angles are equal, alternate interior angles are equal, and same side interior angles are supplementary.

Front

Calculate the measure of angle 4 if angle 6 is 96 degrees and they are Same Side Interior Angles.

Back

Angle 4 = 180 - 96 = 84 degrees.

Front

If angle Z is 128 degrees, what is the measure of its corresponding angle?

Back

The corresponding angle is also 128 degrees.

Front

Find the measure of angle A if angle B is 80 degrees and they are Alternate Interior Angles.

Back

Angle A = 80 degrees.

Front

What is the relationship between Same Side Interior Angles?

Back

Same Side Interior Angles are supplementary, meaning their measures add up to 180 degrees.

Front

If angle 1 is 49 degrees, what is the measure of angle 2 if they are Corresponding Angles?

Back

Angle 2 = 49 degrees.
