A rectangular prism has three pairs of parallel faces. Each pair consists of two opposite faces that are identical in shape and size: two pairs of rectangular faces on the top and bottom, two pairs on the front and back, and two pairs on the left and right sides. Thus, there are a total of three pairs of parallel faces.
a trapizoid
If a cut is made parallel to the base of a cone, the shape of the cross section is a circle. This circular cross section maintains the proportional dimensions of the cone's base, and its radius decreases as the cut moves closer to the apex of the cone. The resulting circles are similar to the base of the cone but vary in size depending on the height at which the cut is made.
a parallelogram
rhombus
When a right circular cone is intersected by a plane that is parallel to one of its edges, the resulting shape produced is a circular section or a circular slice of the cone. This occurs because the plane cuts through the cone in such a way that it maintains a constant distance from the axis of the cone, creating a cross-section that is a circle. The size of this circle depends on the position of the cut along the height of the cone.
