11D Angles formed by Parallel Lines and a Transversal

Front

What are alternate interior angles?

Back

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

Front

What are alternate exterior angles?

Back

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

Front

What are same-side interior angles?

Back

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

Front

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

Back

Corresponding angles are equal.

Front

If angle 6 is 25 degrees, what is the measure of angle 7 if they are same-side interior angles?

Back

Angle 7 is 155 degrees.

Front

What is the sum of the measures of same-side interior angles when two parallel lines are cut by a transversal?

Back

The sum is 180 degrees.

Front

How do you identify corresponding angles?

Back

Corresponding angles are in the same position relative to the parallel lines and the transversal.

Front

What is the relationship between alternate interior angles when two parallel lines are cut by a transversal?

Back

Alternate interior angles are equal.

Front

What is the measure of angle 1 if it is an exterior angle and angle 2 is 113 degrees?

Back

Angle 1 is 113 degrees.

Front

What is the definition of a transversal?

Back

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