a tetrahedon
A tetrahedron has 4 vertices and 4 faces.
A tetrahedron has 4 vertices's, 6 edges, and 4 faces. Each face is a triangle.It looks like a triangle based pyramid.

6 edges and 4 corners
Four. The prefix "tetra" means four.
There is no such shape. A tetrahedron has 6 edges, but it is NOT a prism.
a tetrahedon
None. Each face is an equilateral triangle.
A tetrahedron has 4 vertices and 4 faces.
None because a tetrahedron is a triangular based pyramid with 4 faces, 6 edges and 4 vertices
A pyramid is a generic term which is used to describe a 3-dimensional shape that consists of a polygonal face (normally called the base) with n sides, and n triangular faces (called lateral faces) attached to each edge of the polygon and meeting at an apex above the base. A pyramid, whose base is an n-sided polygon has n+1 faces, n+a vertices and 2n edges. Only the tetrahedon has 4 axes of symmetry. Most pyramids have none.
