Question

look at this diagram: if $overleftrightarrow{ik}$ and $overleftrightarrow{ln}$ are parallel lines and $mangle ijh = 56^{circ}$, what is $mangle kjm$?

Explanation:

Step1: Identify angle - relationship

$\angle IJH$ and $\angle KJM$ are vertical angles.

Step2: Apply vertical - angle property

Vertical angles are congruent. So $m\angle KJM=m\angle IJH$.

Answer:

$56$
