The possible names for that angle are:
1.- GFE
2.- EFG
3.- 4
4.- F
5.-
This is the picture of that angle
It is an obtuse angle so it measures more than 90°.
When we name an angle the vertex is in the middle of the name.
For example, here we have the angle ABC, that means that B is the vertex (is in the middle) and A and C are the corners.
The Line BD bisects the angle, this line must be draw from B because it is named as BD.
