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 Vertical Angles?

Back

Vertical Angles are the angles opposite each other when two lines intersect. They are always equal in measure.

Front

What is the definition of Parallel Lines?

Back

Parallel Lines are two lines in a plane that never meet or intersect, no matter how far they are extended.

Front

What is the relationship between 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 is the value of y if the Same Side Interior Angles are 29 degrees and y degrees?

Back

y = 180 - 29 = 151 degrees.

Front

If two lines are parallel, what can be said about the Alternate Interior Angles?

Back

Alternate Interior Angles are equal when two parallel lines are cut by a transversal.

Front

What is the measure of angle 5 if it is a Corresponding Angle to a 65-degree angle?

Back

Angle 5 = 65 degrees.

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

If one angle measures 60 degrees, what is the measure of its Linear Pair?

Back

The Linear Pair angle = 180 - 60 = 120 degrees.

Front

What is the relationship between Same Side Exterior Angles?

Back

Same Side Exterior Angles are supplementary when two parallel lines are cut by a transversal.
