Honors Parallel Lines & Transversals

Front

What are parallel lines?

Back

Parallel lines are lines in a plane that never meet; they are always the same distance apart.

Front

What is a transversal?

Back

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

Front

What are alternate exterior angles?

Back

Alternate exterior angles are pairs of angles that lie outside the two lines and on opposite sides of the transversal.

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in the same position on two different lines cut by a 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 when two parallel lines are cut by a transversal.

Front

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

Back

Corresponding angles are equal when two parallel lines are cut by a transversal.

Front

What is the sum of the angles on a straight line?

Back

The sum of the angles on a straight line is 180 degrees.

Front

What is the measure of a right angle?

Back

A right angle measures 90 degrees.

Front

If two angles are supplementary, what is the relationship between their measures?

Back

Supplementary angles add up to 180 degrees.

Front

If angle 1 is 45 degrees, what is the measure of angle 5 if they are corresponding angles?

Back

Angle 5 is also 45 degrees because corresponding angles are equal.
