Identifying Angle Pairs

Front

What are Alternate Exterior Angles?

Back

Angles that lie on opposite sides of the transversal and outside the parallel lines.

Front

What is the definition of Supplementary Angles?

Back

A pair of angles that add up to 180 degrees.

Front

What type of angle pair are angles 1 and 8 if they are on opposite sides of the transversal?

Back

Alternate Exterior Angles.

Front

What is the measure of the missing angle if one angle is 130 degrees?

Back

50 degrees (since 180 - 130 = 50).

Front

Identify the Alternate Exterior Angles in the following scenario: Two parallel lines cut by a transversal. Which angles are Alternate Exterior?

Back

Angles 5 and 4.

Front

What are Alternate Interior Angles?

Back

Angles that lie on opposite sides of the transversal and between the parallel lines.

Front

What are Same-Side Interior Angles?

Back

Angles that lie on the same side of the transversal and between the parallel lines.

Front

What is the definition of Complementary Angles?

Back

A pair of angles that add up to 90 degrees.

Front

What are Vertical Angles?

Back

Angles that are opposite each other when two lines intersect; they are always equal.

Front

If two angles are a Linear Pair, what is true about their measures?

Back

They are supplementary, meaning they add up to 180 degrees.
