Ok, we have:
*Adjacent angle: Two angles are adjacent when they have a common side and a common vertex and don't overlap.
*Vergical Angle: Vertical angles are each of the pairs of opposite angles made by two intersecting lines.
*Complementary Angles: Two angles are complementary when their measures add to 90°.
*Supplementary Angles: Two angles are supplementary when their measures add to 180°.
*Linear Pair: A linear pair of angles is when two lines intersect. These angles are said to be linear if they are adjacent angles formed by two inersecting lines.
*Linear Pair Postulate: "If two angles form a linear pair, then the angles are supplementary."
*Angle Bisector: Is the line or segment of line that divides the angle nto two equal parts.
