Hey there Mr. Nooby!
Let's consider, what are [tex](vertical \ angles) [/tex] anyways?
Vertical angle are [tex]\boxed{ opposite \ angles \ made \ by \ two \ intersecting \ lines}[/tex]
So,from looking from above, we will then consider this.
[tex]\boxed{AFC} \ and \ also \ \boxed{DFB}[/tex]
Hope this helps you greatly!
