Transversal Angle Relationships

Front

What is the definition of Alternate Interior Angles?

Back

Angles that are on opposite sides of the transversal and inside the two lines.

Front

What is the definition of Alternate Exterior Angles?

Back

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

Front

What are Corresponding Angles?

Back

Angles that are in the same position on two parallel lines in relation to the 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 is the relationship between Vertical Angles?

Back

Vertical angles are opposite angles formed by the intersection of two lines and are always equal.

Front

If two parallel lines are cut by a transversal, what can be said about Alternate Interior Angles?

Back

They are equal.

Front

If two parallel lines are cut by a transversal, what can be said about Same-Side Interior Angles?

Back

They are supplementary (add up to 180 degrees).

Front

What is the sum of the measures of Same-Side Interior Angles?
