Question

The base of a cube is parallel to the horizon. If the cube is cut by a plane to form a cross section, under what circumstance can the cross section be a non-rectangular parallelogram?

when the plane cuts three faces of the cube, separating one corner from the others

when the plane passes through a pair of vertices that do not share a common face


when the plane is perpendicular to the base and intersects two adjacent vertical faces


when the plane makes an acute angle to the base and intersects three vertical faces


not enough information to answer the question

@CGGURUMANJUNATH can you help me???

Answer 2

is it when the plane makes an acute angle to the base and intersects three vertical faces

Answer 3

@jim_thompson5910 can you help me please?

Answer 4

To create a non-rectangular parallelogram, slice with a plane from the top face to the bottom. The slice cannot be parallel to any side of the top face, and the slice must not be vertical. This allows the cut to form no 90° angles. One example is to cut through the top face at a corner and a midpoint of a non-adjacent side, and cut to a different corner and midpoint in the bottom face.
