A tetrahedron is a triangular pyramid. It has six edges, four faces and four vertices.
A closed three-dimensional figure formed by four or more polygons that intersect only at their edges is called a polyhedron. It contains flat faces, straight edges, and sharp corners or vertices.
4 faces, 6 edges, 4 verticesFour faces, six edges and four vertices.
Rectangles are plane (2-dimensional) polygons. Only solid (3-dimensional) polyhedrons have faces.
a sphere has no edgesOf the solids with planar faces and line edges the tetrahedron has the fewest edges and faces. (Four faces and six edges)
There is no solid figure with only four edges. The smallest solid figure is the tetrahedron, made up of four triangular faces, but it has six edges.
Tetrahedron
A tetrahedron has four faces and six edges.
Any solid object with six faces is a hexahedron. A regular hexahedron (with 12 edges) is a cube where all the faces are squares An irregular hexahedron (with 12 edges) is a cuboid where two faces are equal squares and four are equal rectangles.
A tetrahedron, otherwise known as a triangular pyramid, has four faces, four vertices and six edges.
A tetrahedron is a polyhedron with four triangular faces, six edges, and four vertices. It is a three-dimensional shape formed by connecting four equilateral triangles at their edges, resembling a pyramid with a triangular base.
A square is not a solid figure at all. It's a flat figure, with four congruent faces and four congruent angles.
A tetrahedron or triangular-based pyramid has four faces, six edges, and four vertices.
Triangular pyramid.
square-based pyramid
A cuboid.
A three-dimensional figure or shape, such as a tetrahedron, has four faces. These faces are equilateral triangles. A tetrahedron also has four vertices and 6 edges.
