5.1 practice - Parallel Lines & Transversals

Front

What are Vertical Angles?

Back

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

What is the Corresponding Angle Postulate?

Back

When a transversal crosses two parallel lines, each pair of corresponding angles is equal.

Front

Define Alternate Interior Angles.

Back

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

What are Alternate Exterior Angles?

Back

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

What is a Linear Pair of Angles?

Back

A linear pair of angles consists of two adjacent angles that form a straight line. They are supplementary, meaning their measures add up to 180 degrees.

Front

If angle 4 is 92°, what is the measure of angle 8?

Back

Angle 8 is also 92° because they are corresponding angles.

Front

What is the measure of angle 5 if angle 6 is 88°?

Back

Angle 5 is 92° because angle 5 and angle 6 are supplementary.

Front

How do you find the measure of an angle when given its supplementary angle?

Back

To find the measure of an angle when given its supplementary angle, subtract the measure of the supplementary angle from 180°.

Front

What is the relationship between angle 1 and angle 3 if they are a linear pair?

Back

Angle 1 and angle 3 are supplementary angles, meaning their measures add up to 180°.
