Parallel Lines and Transversals

Front

What are Vertical Angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always equal.

What is a Transversal?

Back

A transversal is a line that passes through two or more lines in the same plane, intersecting them.

Front

What is the relationship between Corresponding Angles?

Back

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

What are Alternate Interior Angles?

Back

Alternate interior angles are pairs of angles on opposite sides of a transversal but inside the two lines. They are equal when the lines are parallel.

What are Alternate Exterior Angles?

Back

Alternate exterior angles are pairs of angles on opposite sides of a transversal but outside the two lines. They are equal when the lines are parallel.

If angle 5 is 130 degrees, what is the measure of angle 6 if they are alternate interior angles?

Back

Angle 6 is also 130 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.

Front

How do you identify corresponding angles?

Back

Corresponding angles can be identified as angles that occupy the same relative position at each intersection of the transversal with the two lines.
