Front

What are Alternate Exterior Angles?

Back

Angles that are on opposite sides of a transversal and outside the two lines it intersects.

Front

What are Supplementary Angles?

Back

Two angles that add up to 180 degrees.

Front

Identify the pair of Alternate Exterior Angles: Angle 8 and Angle 1 or Angle 2 and Angle 6?

What are Alternate Interior Angles?

Back

Angles that are on opposite sides of a transversal and between the two lines it intersects.

Front

What are Corresponding Angles?

Back

Angles that are in the same position on two parallel lines in relation to a transversal.

Front

What is a Linear Pair?

Back

A pair of adjacent angles that are supplementary, meaning they add up to 180 degrees.

Front
