From the given figure, let's answer the following questions.
a) GB:
Point G and Point B lie on the same plane(m).
Since the points lie on the same plane, we can say they are coplanar points
b) DE:
Point D and Point E are points that lie on the same line.
Since they lie on the same line, we can say they are collinear points.
ANSWER:
GB: Coplanar
DE: Collinear
