Review: Parallel Lines & Transversals

Front

What is a Linear Pair of Angles?

Back

A Linear Pair of Angles consists of two adjacent angles that form a straight line. The sum of their measures is 180 degrees.

Front

What are Alternate Exterior Angles?

Back

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

Front

What is the relationship between Same-Side Interior Angles?

Back

Same-Side Interior Angles are interior angles that lie on the same side of the transversal. If the lines are parallel, their measures add up to 180 degrees.

Front

Define Corresponding Angles.

Back

Corresponding Angles are pairs of angles that are in the same position on two different lines cut by a transversal. They are equal when the lines are parallel.

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

How do you find the measure of an angle in a Linear Pair?

Back

To find the measure of an angle in a Linear Pair, subtract the measure of the known angle from 180 degrees.

Front

What is the significance of Alternate Interior Angles?

Back

Alternate Interior Angles are equal when the two lines are parallel, which helps in proving lines are parallel.

Front

Explain the concept of Same-Side Exterior Angles.

Back

Same-Side Exterior Angles are exterior angles that lie on the same side of the transversal. If the lines are parallel, their measures add up to 180 degrees.

Front

What is the relationship between Corresponding Angles and parallel lines?

Back

If two lines are parallel, then each pair of corresponding angles is equal.

Front

How do you identify Vertical Angles in an intersection?

Back

Vertical Angles are formed by two intersecting lines and are located opposite each other.
