Answer:
<h2>d. GO = OD</h2>
Step-by-step explanation:
The choices are
a. O, G and D are collinear.
b. O, G and D are coplanar.
c. GO + OD = GD
d. GO = OD
If point O is between points G and D, it's true that: GO + OD = GD, by sum of segments.
We know that point O divides segment GD in two parts, but we don't know if it's an equal division to say GO = OD, we don't enough information to say that.
Therefore, the right answer is d.
Because each partition is not necessarily equal, because the problem doesn't say that Point O is a middle-point.
