A linear pair is a pair of adjacent angles formed when two lines intersect. In the figure, ∠1 and ∠2 form a linear pair. So do ∠2 and ∠3 , ∠3 and ∠4 , and ∠1 and ∠4 .

Which of the following is an example of linear pair?

A ladder placed against the wall is a real-life example of Linear Pair. Here, the ‘angle A’ formed by placing the ladder against the wall is adjacent to ‘angle B. ‘ Both the angles formed have a common vertex and the sum equal to 180 degrees.

What is a linear pair Class 7?

A linear pair is a pair of adjacent angles whose non-common arms are opposite rays and sum of these adjacent angles is 180°.
