corresponding angles two nonadjacent angles made by the crossing of two lines by a third line, one angle being interior, the other exterior, and both being on the same side of the third line.
supplementary angles Two angles whose sum is 180°.
complimentary angles Two angles whose sum is 90°
vertical angles Two angles formed by two intersecting lines and lying on opposite sides of the point of intersection.
alternate interior angles Alternate interior angles are congruent which lie on different parallel lines and on opposite sides of a transversal.
alternate exterior angles Alternate exterior angles are congruent, two exterior angles on opposite sides of a transversal which lie on different parallel lines.
exterior angles An angle between one side of a polygon and the extension of an adjacent side. Note: The sum of the exterior angles of any convex polygon is 360°. This assumes that only one exterior angle is taken at each vertex.
Diagonals A line segment connecting non-adjacent vertices of a polygon.
