If the sum of two adjacent angles is , they are said to form a linear pair.
and are linear pair of angles and their sum is i.e.,
Illustration : In the following figure are adjacent angles.Whether they form a linear pair or not and name the straight line if formed ?
Solution: As 140+40 = 180 Hence the given pair forms a pair of linear angles and AOC is a straight line.
Illustration : It is given that and XY is produced to a point P. Draw a figure from the given information. If ray YQ bisects find and reflex
Solution: It is given that ray YQ bisects SO, let
Since QY stands on ray PX. (Linear Pair)2x + 64 = 1802x = 180 - 642x = 116hence x = 58.and, reflex |
