2. a triangle by vertical bisection
3. a trapezoidal by diagonal bisection

Final answer:

A rectangular pyramid can have three different cross sections depending on how it is cut: a horizontal bisection results in a rectangle, a vertical bisection results in a triangle, and a diagonal bisection results in a trapezoid. Each cross section reveals different aspects of the pyramid's shape.

Step-by-step explanation:

When we cut a rectangular pyramid in different ways, we can obtain various cross-sectional shapes:

  1. A horizontal bisection through a rectangular pyramid results in a rectangle. This is because when the pyramid is cut parallel to its base, the shape of the base, which is a rectangle, is replicated.
  2. A vertical bisection through the center of the pyramid results in a triangle. The apex of the pyramid forms the tip of the triangle, and the base of the cut forms the base of the triangle.
  3. A diagonal bisection produces a trapezoid. Diagonal cutting across the pyramid at an angle to one of the edges means the slice will have one pair of parallel sides (the top is parallel to a corresponding edge at the base) and two non-parallel sides.

Each cross section provides a different perspective on the shape of the pyramid and can reveal different properties, such as symmetry and proportions.
