Question

which angles form a linear pair? ∠prl and ∠lrm ∠orp and ∠mrn ∠mrn and ∠nro ∠lrp and ∠orp

Explanation:

Step1: Recall the definition of a linear pair

A linear pair of angles is a pair of adjacent angles whose non - common sides are opposite rays.

Step2: Analyze each option

• For $\angle PRL$ and $\angle LRM$: Their non - common sides are not opposite rays.
• For $\angle ORP$ and $\angle MRN$: They are not adjacent.
• For $\angle MRN$ and $\angle NRO$: Their non - common sides are not opposite rays.
• For $\angle LRP$ and $\angle ORP$: They are adjacent and their non - common sides ($RL$ and $RO$) are opposite rays.

Answer:

$\angle LRP$ and $\angle ORP$
