When a square pyramid is sliced by a plane parallel to its base, the cross section formed is a smaller square. The size of the square depends on the distance from the apex of the pyramid to the slicing plane; as the plane moves downward, the area of the square decreases proportionally. This maintains the shape's similarity to the base of the pyramid.
When a pyramid is sliced at an angle, the shape formed depends on the angle and position of the cut. If the slice is made parallel to the base, a smaller, similar pyramid is created. If the cut is made at an angle that is not parallel to the base, the resulting shape is typically a trapezoid or a polygon, depending on the specific geometry of the slice and the original pyramid.
The shape of a pyramid without its top is called a frustum. A frustum is formed when a pyramid is sliced parallel to its base, resulting in a truncated shape that has two parallel bases: one larger and one smaller. This geometric figure retains the original triangular faces of the pyramid, minus the apex.
The cross-section of a rectangular pyramid sliced by a plane will typically result in a polygonal shape. If the cutting plane is parallel to the base of the pyramid, the cross-section will be a smaller rectangle. If the plane intersects the sides at an angle, the resulting cross-section may be a trapezoid or a triangle, depending on the height at which the slice occurs. The specific shape can be described by points W, X, Y, and Z, which would represent the vertices of the cross-section.
When a cone is sliced by a slanted plane, the cross section formed is typically an ellipse. The exact shape can vary depending on the angle and position of the plane relative to the cone. If the plane is parallel to the cone's base, the cross section will be a circle; if it intersects the cone at a steeper angle, the resulting shape will be an ellipse.

The horizontal cross-section of a pyramid forms a square when the pyramid has a square base and is sliced parallel to that base. This is because all points on the cross-section are equidistant from the center of the base, maintaining the same proportions as the base itself. As the cut is made at any height, the resulting shape remains a square, regardless of the height of the slice. If the pyramid's base were a different shape, the cross-section would reflect that shape instead.
When a square pyramid is sliced perpendicular to its base through a vertex, the cross section will be a triangle. This triangle will have one vertex at the apex of the pyramid and the other two vertices on the base, forming a triangular shape that includes one of the pyramid's edges and a segment of the base. The resulting triangle will be isosceles if the slice is made symmetrically.
The vertical cross section of a square pyramid is a triangle. When the pyramid is sliced vertically through its apex and down to the base, the resulting shape is a triangular profile that includes the apex at the top and the edges of the base at the bottom. The height of the triangle corresponds to the height of the pyramid, while the base of the triangle spans the width of the base of the pyramid.
The 2D parallel shape that represents a cross section of a cylinder is a circle. When a cylinder is sliced parallel to its base, each cross section reveals a circular shape, regardless of where the cut is made along the height of the cylinder. This circular cross section maintains the same diameter as the bases of the cylinder.
When a cone is sliced, the shape formed depends on the angle of the cut. If the cut is parallel to the base of the cone, a circular shape is formed. If the cut is made at an angle to the base, an ellipse is created. A vertical slice through the apex and down the side will result in a triangular shape.
They would be two right triangular pyramids.
In a polyhedron - a 3-dimensional object - a pair of parallel faces are two faces which lie in planes that are parallel to each other.Parallel faces need not be congruent. For example, consider a pyramid whose top is sliced off by a plane parallel to it base. The flat top and the base will be parallel faces but will not be congruent.
