Parallel Lines and Transversals

Front

What are parallel lines?

Back

Parallel lines are lines in a plane that never meet or intersect, no matter how far they are extended. They are always the same distance apart.

What is a transversal?

Back

A transversal is a line that crosses at least two other lines. When a transversal intersects parallel lines, it creates several angles.

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in similar positions at each intersection where a transversal crosses two lines. If the lines are parallel, corresponding angles are congruent.

What are alternate interior angles?

Back

Alternate interior angles are pairs of angles that lie between two lines and on opposite sides of a transversal. If the lines are parallel, these angles are congruent.

What are alternate exterior angles?

Back

Alternate exterior angles are pairs of angles that lie outside two lines and on opposite sides of a transversal. If the lines are parallel, these angles are congruent.

What are consecutive interior angles?

Back

Consecutive interior angles are pairs of angles that lie between two lines on the same side of a transversal. If the lines are parallel, these angles are supplementary.

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

Back

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

What is the supplement of an angle?

Back

The supplement of an angle is what, when added to the angle, equals 180 degrees.
