Question

what is the relationship between $\angle por$ and $\angle ros$?
\bigcirc complementary angles
\bigcirc supplementary angles
\bigcirc adjacent angles
\bigcirc none of the above

Explanation:

Step1: Identify ∠POR measure

From the diagram, $\angle POR = 90^\circ$ (right angle marker).

Step2: Identify ∠ROS measure

Since $\angle POR + \angle ROS = 180^\circ$ (straight line MR), $\angle ROS = 180^\circ - 90^\circ = 90^\circ$.

Step3: Check angle relationship

Sum: $\angle POR + \angle ROS = 90^\circ + 90^\circ = 180^\circ$. Supplementary angles sum to $180^\circ$.

Answer:

Supplementary angles
