Parallel Lines

lines in the same plane that never intersect

Transversal

a line that intersects two or more lines

Corresponding Angles

Angles formed by a transversal cutting through 2 or more lines that are in the same relative position. If lines are parallel, these angles are congruent.

Alternate Interior Angles

Angles that are non-adjacent interior angles that lie on OPPOSITE sides of the transversal. If the lines are parallel, these angles are congruent.

Alternate Exterior Angles

Angles that are non-adjacent exterior angles that lie on OPPOSITE sides of the transversal. If lines are parallel, these angles are congruent.

80�

Find the measure of the indicated angle.

125�

Find the measure of the indicated angle.

supplementary angles

Angles that add to 180 degrees.

complementary angles

Angles that add up to 90 degrees

180 degrees

The number of degrees in a triangle.
