equilateral triangles-Apex ;)
regular pentagons.... Kyah!
A tetrahedron has four faces.
A three dimensional figure with polygonal faces is called a polyhedron. Specific names draw from the Latin prefixes. For example a four sided figure is a tetrahedron.
A tetrahedron has 4 faces.
4 faces
equilateral triangles-Apex ;)
Triangle (tetrahedron, octahedron, icosahedron) Square (cube) Pentagon (dodecahedron)
There are points (vertices) lines (edges) and polygons (faces).
The polygons are the equilateral triangle, the square, and the regular pentagon. The faces of these platonic solids are made from the following polygons: tetrahedron - 4 triangles cube - 6 squares octahedron - 8 triangles dodecahedron - 12 pentagons icosahedron - 20 triangles
Triangles.
Equilateral triangles
A tetrahedron has 4 faces.
regular pentagons.... Kyah!
A tetrahedron has four faces.
Polygons aren't normally described as having faces Polyhedrons are normally described as having faces So it could be a tetrahedron which is a triangular based pyramid
There are four number of faces in a tetrahedron.
Because a tetrahedron is a triangular based pyramid that has 4 identical faces and 4 faces meet at all the vertices.
