3.1 Angle Pairs

Front

What are Alternate Interior Angles?

Back

Angles that are on opposite sides of a transversal and inside 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 are Same Side Interior Angles?

Back

Angles that are on the same side of the transversal and inside the two lines.

Front

What are Alternate Exterior Angles?

Back

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

Front

How do you identify Corresponding Angles in a diagram?

Back

Look for angles that are in the same relative position at each intersection of the transversal with the parallel lines.

Front

What is the relationship between Alternate Interior Angles when the lines are parallel?

Back

They are equal in measure.

Front

What is the relationship between Same Side Interior Angles when the lines are parallel?

Back

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

Front

If two lines are cut by a transversal and the Alternate Exterior Angles are equal, what can be concluded?

Back

The two lines are parallel.

Front

What is the definition of a transversal?

Back

A line that intersects two or more lines at different points.

Front

How can you classify angle pairs formed by a transversal?

Back

By their positions relative to the parallel lines and the transversal: Alternate Interior, Alternate Exterior, Corresponding, Same Side Interior, and Same Side Exterior.
