Question

look at this diagram: if $overleftrightarrow{fh}$ and $overleftrightarrow{ik}$ are parallel lines and $mangle ijg = 51^{circ}$, what is $mangle kjl$?

Explanation:

Step1: Identify vertical - angle relationship

$\angle IJG$ and $\angle KJL$ are vertical angles.

Step2: Recall vertical - angle property

Vertical angles are congruent, so $m\angle KJL=m\angle IJG$.

Answer:

$51$
