Question

look at this diagram: if $overleftrightarrow{ce}$ and $overleftrightarrow{fh}$ are parallel lines and $mangle cdg = 70^{circ}$, what is $mangle edb$?

Explanation:

Step1: Identify vertical - angle relationship

$\angle CDG$ and $\angle EDB$ are vertical angles.

Step2: Recall vertical - angle property

Vertical angles are congruent, so $m\angle EDB=m\angle CDG$.

Answer:

$70^{\circ}$
