Parallel Lines and Transversals

Front

What is a transversal?

Back

A transversal is a line that passes through two or more parallel lines, creating angles with those lines.

Front

What are corresponding angles?

Back

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

Front

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

Back

Alternate interior angles are equal.

Front

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

Back

The sum of the interior angles of a triangle is always 180 degrees.

Front

If angle 1 is 70 degrees, what is the measure of angle 5 if angle 1 and angle 5 are corresponding angles?

Back

Angle 5 is also 70 degrees.

Front

What is the relationship between same-side interior angles when two parallel lines are cut by a transversal?

Back

Same-side interior angles are supplementary, meaning they add up to 180 degrees.

Front

Find the value of x if angle 3 is 47 degrees and angle 3 and angle x are alternate exterior angles.

Back

x = 47 degrees.

Front

What is the definition of parallel lines?

Back

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

Front

If angle 2 is 130 degrees, what is the measure of angle 4 if angle 2 and angle 4 are alternate interior angles?

Back

Angle 4 is also 130 degrees.

Front

What is the measure of the missing angle if angle 6 is 50 degrees and angle 6 and the missing angle are same-side interior angles?

Back

The missing angle is 130 degrees.
