Which points in the figure below are coplanar with points a and b

a) points d and h
b) points f and i
c) points g and c
d)points i and g

These two points are on the front panel along with points A and B

Choice B is not the answer since points A,B,F are on the floor panel, but point I is not on the floor panel (instead its on the right wall panel)

Choice C is not the answer as points G and C are in the ceiling panel, while A and B are in the floor panel and front wall panel.

Choice D is not the answer for similar reasoning as choice B not being the answer.

Points are considered coplanar if they are in the same plane. A plane can be thought of as a flat piece of paper that does not bend or curve.
