J is on the segment EH. Which planes contain this segment?
Example Solution: Plane ADJ and plane EHG
Practice makes perfect
The point J is on the segment EH, which is an edge that belongs to the front and to the bottom of the cube. Moreover, these two faces belong to two different planes.
To define each plane, we need three non-collinear points that are contained within the plane.
Front:& A,D and J
Bottom:& E,H and G
This gives us two planes containing point J: plane ADJ and plane EHG.
