LINES AND ANGLES
  1. Corresponding Angles
    1. Corresponding angles are the angles on the same side of the transversal.
    2. Alternate Angles
      1. Alternate Interior Angles
        1. Angles opposite to each other in the interior of the lines
        2. Alternate Exterior Angles
          1. Angles opposite to each other on exterior of the lines.
        3. Co-Interior Angles
          1. Angles which lie between two lines on the same side of the transversal.
          2. Linear Pair
            1. Adjacent angles which add up to 180°.
            2. Supplementary Angles
              1. A pair of angles which add up to 180°. (They might not be adjacent).
              2. Complementary Angles
                1. A pair of angles which add up to 90°.(They might not be adjacent).
                2. Transversal
                  1. A line that intersects two or more lines at distinct points.
                  2. Adjacent Angles
                    1. A pair of angles which have the common vertex and a common arm
                    2. Vertically Opposite Angles
                      1. These angles are formed when two lines intersect each other and form 4 angles. The angles opposite to each other are vertically opposite angles.
                        1. Vertically opposite angles are always equal.
                      2. An Angle is formed when two rays intersect (meet) each other.
                        1. Interior Angles
                          1. Angles which lie inside the two lines, cut by the transversal.
                          2. Exterior Angles
                            1. Angles which lie outside the two lines, cut by the transversal.
                            2. When two PARALLEL lines are cut by a transversal many properties come in action.
                              1. Each Pair of corresponding angles are equal.
                                1. Each pair of alternate interior angles are equal.
                                  1. Each pair of alternate exterior angles are equal.
                                    1. Co-interior angles are supplementary.
                                    2. Parallel lines a lines which never intersect.
