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
5 vertices
2 lines of symmetry
6 edges and 4 corners
There is no such shape. A tetrahedron has 6 edges, but it is NOT a prism.
A tetrahedron has 4 vertices's, 6 edges, and 4 faces. Each face is a triangle.It looks like a triangle based pyramid.
a tetrahedon
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.
A tetrahedron is a three-dimensional figure with four equilateral triangles. Every pyramid with a triangle as the base is a tetrahedron.
A rectangle has 4 faces: 2 long faces and 2 short faces.
