transversal

a line that intersects two coplanar lines in two different points


alternate exterior angles

two nonadjacent exterior angles on opposite sides of the transversal


sameside interior angles

two interior angles on the same side of the transversal


convex polygon

a polygon whose exterior angles measure 360 and whose diagonals all lie in the interior of the polygon


parallel planes

planes that do not intersect


alternate interior angles

two nonadjacent interior angles on opposite sides of the transversal


skew lines

lines that are not coplanar and do not intersect


auxiliary line

a line added to a figure, often used to help prove a proof


regular polygon

a polygon that is both quilateral and equiangular


remote interior angles

the two angles of the triangle that are not adjacent to the exterior angle


diagonal of a polygon

a segment joining two nonconsecutive vertices


corresponding angles

two nonadjacent angles on the same side of the transversal such that one is an exterior angle and the other is an interior angle


exterior angle of a triangle

forms a linear pair with the adjacent interior angle of the triangle


parrallel lines

coplanar lines that do not intersect
