Parallel lines - Two or more coplanar lines that do not intersect. Parallel line segments or rays are line segments or rays that are subsets of parallel lines., Transversal - A line that intersects two (or more) other lines in distinct points, Alternate interior - Any two nonadjacent angles that lie on opposite sides of a transversal and that are interior to the lines. Note: As illustrated in the second example, the lines do not need to be parallel., Alternate exterior - Any two nonadjacent angles that lie on opposite sides of a transversal and that are exterior to the lines. Note: As illustrated in the second example, the lines do not need to be parallel., Corresponding angles - A set of angles formed on each of two or more lines cut by a transversal that are in the same position relative to each line and to the transversal. Note: As illustrated in the second example, the lines do not need to be parallel., Consecutive interior - Any two nonadjacent angles that lie on the same sides of a transversal and that are interior to the lines. Note: As illustrated in the second example, the lines do not need to be parallel., Supplementary angles - Two angles the sum of whose measures is 180 degrees., Adjacent angles - Two coplanar angles that share a common vertex and a common side but have no common interior points., Complementary angles - Two angles the sum of whose measures is 90 degrees., Vertical angles - The two nonadjacent angles formed when two lines intersect, Congruent - Having the same size and shape,
