alternate interior angles - a pair of angles that are between the two parallel lines and on opposite sides of the transversal (These angles are congruent.)
corresponding angles - angles that are in the same location relative to the transversal but with one of each of the two parallel lines (These angles are congruent.)
exterior angles (of parallel lines cut by a transversal) - angles outside (not between) the parallel lines
exterior angle (of a polygon) - the angle form by extending one side of a polygon
perpendicular bisector - a line that cuts a segment into tow congruent parts and is perpendicular to the segment
same side interior angles - angles on the same side of the transversal and between the tow parallel lines (These angles are supplementary.)
transversal - a line that cuts a pair of lines in exactly two places
