parallel lines cut by a transversal - evans 2022

Front

What are parallel lines?

Back

Lines in a plane that never meet and are always the same distance apart.

Front

What is a transversal?

Back

A line that crosses at least two other lines in the same plane.

Front

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

Back

Corresponding angles are equal.

Front

What are alternate interior angles?

Back

Angles that are on opposite sides of the transversal and inside the two lines; they are equal when the lines are parallel.

Front

What are alternate exterior angles?

Back

Angles that are on opposite sides of the transversal and outside the two lines; they are equal when the lines are parallel.

Front

What are consecutive interior angles?

Back

Angles that are on the same side of the transversal and inside the two lines; they are supplementary when the lines are parallel.

Front

If angle A is 70 degrees, what is the measure of its corresponding angle when two parallel lines are cut by a transversal?

Back

70 degrees.

Front

If angle B measures 135 degrees, what is the measure of the alternate interior angle?

Back

135 degrees.

Front

What is the equation to find the value of x when given angles formed by parallel lines and a transversal?

Back

Set the sum of the angles equal to 180 degrees or use the relationships of corresponding, alternate interior, or alternate exterior angles.

Front

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

Back

180 degrees.
