        1. Vertically Opposite Angles
          1. Alternate Interior Angles
            1. Alternate Exterior Angles
              1. Linear Pair
              2. Parallel lines are always the same distance apart and they never intersect.
                1. A transversal is a line which passes through a pair of parallel lines.
                  1. Alternate Exterior Angles are equal.
                    1. Alternate Interior Angles are equal.
                      1. Co-interior Angles are supplementary.
                        1. Co-exterior Angles are supplementary.
                          1. Corresponding Angles are equal.
                            1. Vertically Opposite Angles are equal.
                            2. An angle is formed when two rays intersect at a point.
                              1. Supplementary Angles - Adjacent Angles which add up to be 180°
                                1. Complementary Angles - Adjacent Angles which add up to be 90°
                                  1. Adjacent Angles - Angles which have a common vertex and a common arm with both the uncommon arms on either sides.
