transversal
a line that intersects two or more other lines
corresponding angles
angles that are in the same position on the two lines in relation to the transversal; are congruent
complementary angles
two angles that add up to 90 degrees; form a right angle
supplementary angles
two angles that add up 180 degrees; form a straight angle (a straight line)
vertical angles
opposite angles; are congruent
alternate interior angles
on opposite sides of the transversal and inside the other two lines; are congruent
alternate exterior angles
on opposite sides of the transversal and outside the other two lines; are congruent
interior angles
formed on the inside of parallel lines that are cut by a transversal
exterior angles
