Answer:

∠MRN and ∠NRO is a linear pair.

Explanation:

Linear pair : A pair of adjacent angles formed by two intersecting lines is called linear pair. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.

A )∠PRL and ∠LRM

According to the definition ∠PRL and ∠LRM is not linear pair .

B)∠ORP and ∠MRN

These angles are formed by the intersection of line OM and PN.

But these angles are vertical angles not adjacent.

Thus ∠ORP and ∠MRN is not a linear pair .

C) ∠MRN and ∠NRO

∠MRN and ∠NRO are formed by the two intersecting lines MO and NP.

Since they these angles are true to the definition.

Thus ∠MRN and ∠NRO is a linear pair.

D)∠LRP and ∠ORP

According to the definition ∠LRP and ∠ORP is not a linear pair .

Hence ∠MRN and ∠NRO is a linear pair.
