Is a cone a Platonic solid?
No, a cone is not a Platonic solid. The Platonic solids are the five regular polyhedra: tetrahedron, cube, octahedron, dodecahedron, and icosahedron.
How are a cone and a pyramid alike?
Start with a regular tetrahedron (triangular based pyramid). As you increase the number of sides in the base of the pyramid, the shape becomes more and more like a right cone. In the limit, the base tends to a polygon with an infinite number of sides - a circle, and the pyramid tends to a right cone.
How is pyramid technically a cone with a polygonal base?
It isn't a cone at all, technically or otherwise, by definition. A cone has a circular base; a pyramid, a polygonal one. In fact I think it's strictly only a pyramid if it has a quadrilateral base - anything else being a "~hedron" where the "~" part describes the number of faces, such as the Tetrahedron (4 triangular faces).
What is a 3D shape that is a tetrahedron?
Well, a tetrahedron has four sides. A regular tetrahedron is a triangular pyramid.
What is a plane face tetrahedron?
A tetrahedron must be plane faced and so, it is just an ordinary tetrahedron.
