Angle package+angle AGD= 180

So AB//CD

Angle pocket = angle AGC

Because the angle 1= angle 2.

So angle EAG= angle AGF

Let the intersection of AG and EF be o.

Because AOE angle and fog angle are diagonal, they are equal.

In the triangle AOE and fog, there are already two equal diagonal angles, so the angle E and the angle F are also equal.
