WebThe tetrahedron is a Platonic solid, which has triangular faces. This figure is also known as a triangular pyramid. The tetrahedron consists of 4 triangular faces, 6 edges, and 4 vertices. The four vertices of the tetrahedron are at similar distances from each other. Unlike other platonic solids, tetrahedra do not have parallel faces. WebIcosahedron has 20 faces, 30 edges, and 12 vertices. ... The tetrahedron, cube, octahedron, icosahedron, and dodecahedron are the only five platonic solids. An icosahedron is the only platonic solid with 20 faces. This is the maximum number of faces a platonic solid can have. WebSep 30, 2024 · A tetrahedron is a polyhedron with 4 faces, 6 edges, and 4 vertices, in which all the faces are triangles. It is also known as a triangular pyramid whose base is also a triangle. How does a tetrahedron have 6 edges? Like all pyramids, the tetrahedron is a polyhedron (i.e. a three-dimensional geometrical shape with flat faces and straight edges). imagine math facts play online
