Answer: The answer is (b) ∠JGI.
Step-by-step explanation: We are given a figure with three concurrent rays, DJ, FH and IE intersecting at the point G.
We are to name an angle that is vertical to ∠DGE.
We know that vertical angles are those angles which are opposite to each other when two lines intersect.
Here, ∠DGE is formed when DJ and IE intersect at G. so, its opposite angle will be ∠JGI.
Therefore, the vertical angle of ∠DGE is ∠JGI.
Thus, (b) is the correct option.
