Question

look at this diagram: if $overleftrightarrow{mo}$ and $overleftrightarrow{pr}$ are parallel lines and $mangle onq = 121^{circ}$, what is $mangle rqs$?

Explanation:

Step1: Identify angle - relationship

$\angle ONQ$ and $\angle RQS$ are corresponding angles.

Step2: Apply property of corresponding angles

For parallel lines $MO$ and $PR$ cut by transversal $L$, corresponding angles are equal. So $m\angle RQS=m\angle ONQ$.

Answer:

$121$
