Parallel Lines Cut by a Transversal Review

Front

What are parallel lines?

Back

Parallel lines are lines in a plane that never meet. They are always the same distance apart and have the same slope.

Front

What is a transversal?

Back

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

Front

What are corresponding angles?

Back

Corresponding angles are angles that are in the same position at each intersection where a transversal crosses two lines.

Front

What is the relationship between alternate interior angles?

Back

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

Front

What are consecutive interior angles?

Back

Consecutive interior angles are supplementary, meaning they add up to 180 degrees when two parallel lines are cut by a transversal.

Front

If angle 1 is 135 degrees, what is the measure of angle 3 if they are corresponding angles?

Back

Angle 3 is also 135 degrees.

Front

If angle C is 116 degrees, what is the measure of its corresponding angle?

Back

The corresponding angle is also 116 degrees.

Front

How do you find the value of x in angle relationships?

Back

Use the properties of angles formed by parallel lines and a transversal, such as corresponding angles, alternate interior angles, and supplementary angles.

Front

What is the measure of angle 2 if it is an alternate exterior angle to angle 3 which is 142 degrees?

Back

Angle 2 is also 142 degrees.

Front

What is the sum of the interior angles on the same side of a transversal?

Back

The sum of the interior angles on the same side of a transversal is 180 degrees.
