Transversals (Return to School)

Front

What is a transversal?

Back

A transversal is a line that intersects two or more lines at distinct 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 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 different lines cut by a 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 alternate interior angles when the lines are parallel?

Back

Alternate interior angles are equal when the lines are parallel.

Front

What is the relationship between corresponding angles when the lines are parallel?

Back

Corresponding angles are equal when the lines are parallel.

Front

What is the relationship between same side interior angles when the lines are parallel?

Back

Same side interior angles are supplementary (add up to 180 degrees) when the lines are parallel.

Front

What are vertical angles?

Back

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

Front

How do you find the measure of an angle when given its supplementary angle?

Back

Subtract the measure of the known angle from 180 degrees.
