Parallel Lines cut by a Transversal

Front

What are parallel lines?

Back

Parallel lines are lines in a plane that never meet and 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 relative to the two lines and the 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

If angle 1 and angle 2 are alternate interior angles, what can be said about their measures?

Back

If angle 1 and angle 2 are alternate interior angles, then their measures are equal.

Front

How do you find the measure of an angle when given its relationship to another angle?

Back

Use the properties of angles formed by parallel lines and a transversal to set up equations based on their relationships.

Front

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

Back

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

Front

What is the sum of the measures of angles around a point?

Back

The sum of the measures of angles around a point is 360 degrees.
