Parallel Lines and Transversals Independent Practice

Front

What is a transversal?

Back

A line that intersects two or more lines (usually parallel lines).

Front

What are alternate interior angles?

Back

Angles that are on opposite sides of the transversal and inside 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 vertical angles?

Back

Angles that are opposite each other when two lines intersect.

Front

What type of angle pair are ∠1 and ∠3 if they are on the same side of the transversal and add up to 180 degrees?

Back

Supplementary angles.

Front

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

Back

They are equal.

Front

If angle 3 is 70 degrees, what is the measure of angle 5?

Back

70 degrees (alternate interior angles are equal).

Front

If angle 1 is 45 degrees, what is the measure of angle 2?

Back

45 degrees (corresponding angles are equal).

Front

What is the sum of the interior angles of a triangle?

Back

180 degrees.

Front

If angle 4 is 115 degrees, what is the measure of angle 6?

Back

115 degrees (alternate interior angles are equal).
