Question

Can someone please help me! I have no idea what I am doing and have no book to look from!

Answer 1

So, angle DGF=180
Clearly since GB bisects this angle,
Angle DGE = angle FGE = x (say)
Then 2x = 180
=> x=90
Clearly both are right angles (90 each)

Answer 2

Explanation:

1) Find DGE

Bisecting an angle makes it half. A straight line is 180

180/2 = DGE

90 = DGE

2) Find FGE

Bisecting an angle makes it half. A straight line is 180

180/2 = FGE

90 = FGE
