Question

look at this diagram: if $overleftrightarrow{ln}$ and $overleftrightarrow{oq}$ are parallel lines and $mangle qpr = 129^{circ}$, what is $mangle nmp$?

Explanation:

Step1: Identify angle - relationship

$\angle QPR$ and $\angle NMP$ are corresponding angles.

Step2: Use property of corresponding angles

When two parallel lines are cut by a transversal, corresponding angles are equal. Given $m\angle QPR = 129^{\circ}$, so $m\angle NMP=m\angle QPR$.

Answer:

$129$
