Supplementary angles

Supplementary angles are pairs of angles that add up to 180 degrees. Thus the supplement of an angle of x degrees is an angle of degrees. If the two supplementary angles are adjacent, their non-shared sides form a straight line. However, supplementary angles do not have to be on the same line, and can be separated in space. For example, adjacent angles of a parallelogram are supplementary, and opposite angles of a cyclic quadrilateral are supplementary. If a point P is exterior to a circle with center O, and if the tangent lines from P touch the circle at points T and Q, then ∠TPQ and ∠TOQ are supplementary. linear pair angles have also been formed by 2 adjacent supplementary angles. The following are properties of a linear pair- ⁕Have a common vertex ⁕Have a common arm ⁕Lie in the either side of the common arm ⁕Sum of their measure is 180 degree. ⁕Their other arm form a straight line
