Linear Pair
LINEAR PAIR
It is a pair of adjacent angles in which the non common arms form a Straight Lines.
| A linear pair of angles is formed when two lines intersect. Two angles are said to be linear if they are adjacent angles formed by two intersecting lines. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees. |  |
|
Illustration: Find the values of the angles x, y and z in each of the following: Solution: 110 + x = 180 : x = 180 - 110 = 70
y = 180 - 80 = 100 (i) Also Y + Z = 180 [Linear pair] 100 + Z = 180 : Z = 180 - 100 = 80
