Transversal lines

Front

What are Corresponding Angles?

Back

Angles that are in the same position on different parallel lines cut by a transversal.

Front

What is a Transversal Line?

Back

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

Front

What are Alternate-Interior Angles?

Back

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

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 sum of angles on a straight line?

Back

180 degrees.

Front

If two parallel lines are cut by a transversal, what can be said about the corresponding angles?

Back

They are equal.

Front

If m∠n = 113°, what is m∠s if ∠s is a corresponding angle?

Back

m∠s = 113°.

Front

What is the relationship between Vertical Angles?

Back

Vertical angles are equal to each other.

Front

If angle 2 is same-side interior with angle 3, what can be said about their measures?

Back

They are supplementary, meaning their measures add up to 180°.

Front

What are Linear Pairs?

Back

Two adjacent angles that form a straight line and are supplementary.
