;select all that apply. which of these polygons is not formed by the cross-section created when a plane intersects a cube? select all that are possible. -square -circle -pentagon -trapezoid -triangle -rectangle

The answer is circle.

Step-by-step explanation:

When a cube is intersected by a plane parallel to its base, a square is created. A rectangle is created when a cube is intersected by a plane in 2 pairs of opposite faces. When a cube is intersected by a plane in 3 adjacent faces, a triangle is formed.

Since a cube does not have any curved faces, so a plane will not be able to intersect it and give a cross section with any curves.

So, a circle is not possible.
