Where are the planes located in the diagram?

Line AE

Practice makes perfect

To begin with, we have to figure out where the two planes are located in the diagram. The points A, E, and H are all on the front face of the cube, so when we extend the front face in all directions, we get plane AEH. Similarly, plane FBE is the left face of the cube extended in all directions.

These planes intersect at the left border of the front face. This occurs along the line AE.
