12/3 Practice of Transversals

Front

What are Corresponding Angles?

Back

Angles that are in the same position on two parallel lines cut by a transversal. They are equal in measure.

Front

What are Alternate Interior Angles?

Back

Angles that lie between two parallel lines on opposite sides of the transversal. They are equal in measure.

Front

What are Consecutive Interior Angles?

Back

Angles that lie between two parallel lines on the same side of the transversal. They are supplementary (add up to 180 degrees).

Front

What are Alternate Exterior Angles?

Back

Angles that lie outside two parallel lines on opposite sides of the transversal. They are equal in measure.

Front

What are Vertical Angles?

Back

Angles that are opposite each other when two lines intersect. They are equal in measure.

Front

What is a Transversal?

Back

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

Front

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

Back

They are equal in measure.

Front

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

Back

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

Front

If Angle R and Angle C are Corresponding Angles, what can be inferred about their measures?

Back

Angle R = Angle C.

Front

If Angle S and Angle A are Alternate Exterior Angles, what can be inferred about their measures?

Back

Angle S = Angle A.
