Question

look at this diagram: if $overleftrightarrow{fh}$ and $overleftrightarrow{ik}$ are parallel lines and $mangle kjl = 119^{circ}$, what is $mangle ijg$? work it out

Explanation:

Step1: Identify angle - relationship

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

Step2: Apply vertical - angle property

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

Answer:

$119$
