Angles Lines and Transversals

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 Alternate Exterior Angles?

Back

Angles that are on opposite sides of a transversal and outside 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 Vertical Angles?

Back

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

Front

What are Same-Side Interior Angles?

Back

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

Front

What are Same-Side Exterior Angles?

Back

Angles that are on the same side of the transversal and outside the two lines it intersects.

Front

What is a Linear Pair?

Back

A pair of adjacent angles whose non-common sides form a straight line; they are supplementary.

Front

How do you identify Alternate Interior Angles in a diagram?

Back

Look for angles that are on opposite sides of the transversal and between the two lines.

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 two lines.

Front

What is the relationship between Vertical Angles?

Back

Vertical angles are always equal in measure.
