... a triangular pyramid. Also known as a tetrahedron.
not possible cause rectangle is a 2D not a 3D figure. it has 4 sides and four right angles at its vertices.
A Triangle.

A Triangular based Pyramid has 4 vertices, 6 edges and 4 faces.
That 3D shape is called triangular pyramid.

A trapezium has 4 vertices and 4 edges or sides. It is a two dimensional figure so it has only one "face".
A 3D sphere has no faces, no edges, and no vertices :) Unlike polyhedrons (like cubes or pyramids), a sphere is a perfectly round solid with a continuous curved surface. It doesn’t have flat faces, straight edges, or corners (vertices). The surface area is calculated using the formula: A = 4 × π × r² So technically: Faces: 0 Edges: 0 Vertices: 0 Hope that clears it up!
