Warmup on Properties of Parallel Lines

Front

What are Same Side Interior Angles?

Back

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

Front

What are Corresponding Angles?

Back

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

Front

What are Alternate Interior Angles?

Back

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

Front

What are Vertical Angles?

Back

Vertical Angles are pairs of angles that are opposite each other when two lines intersect. They are equal in measure.

Front

If angle 1 is 65 degrees, what is the measure of angle 2 if they are corresponding angles?

Back

Angle 2 is also 65 degrees.

Front

If two parallel lines are cut by a transversal, what is the relationship between Same Side Interior Angles?

Back

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

Front

If angle 3 is 110 degrees, what is the measure of angle 4 if they are Alternate Interior Angles?

Back

Angle 4 is also 110 degrees.

Front

What is the value of y if angle 5 is 29 degrees and it is a Same Side Interior Angle with angle 6?

Back

y = 151 degrees (since they are supplementary).

Front

If angle 7 is 60 degrees, what is the measure of angle 8 if they are Vertical Angles?

Back

Angle 8 is also 60 degrees.
