Answer 1

Is there a figure?

Answer 2

What exactly are you lost on?

Answer 3

Without a figure, I'm also lost.

Answer 4

Ok, now I'm already a little less lost.

Answer 5

I will rewrite the figure below and will remove the unnecessary line.
I removed line EF from the drawing because is does not affect our problem.

Answer 6

This is a simpler drawing that makes it easier to understand.
Now look at the two angles of interest, 1 and 4.
When two angles are formed by two intersecting lines and have common endpoint and are not adjacent, they are called vertical angles.
Angles 1 and 4 are vertical angles.

Answer 7

A theorem states:
Vertical angles are congruent.
