Question

Which angles form a linear pair? Helppp

Answer 1

Given:

Pairs of angles in options.

To find:

The angles that form a linear pair.

Solution:

Linear pair: Two angles are called linear pair if they are lie on the same side of a straight line and their sum is 180 degrees.

In the given figure, we have two straight lines MO and NP.

Linear pairs for line MO are

`\angle MRN` and
`\angle NRO`

`\angle MRP` and
`\angle ORP`

`\angle LRM` and
`\angle LRO`

Linear pairs for line NP are

`\angle ORP` and
`\angle NRO`

`\angle MRP` and
`\angle MRN`

`\angle PRL` and
`\angle LRN`

So, pairs of angles in options A, B and D are not linear because they are not lie on the same side of a straight line.

Therefore, the correct option is C.
