Four-sided polygons are usually referred to as quadrilaterals, quadrangles or sometimes tetragons. In geometry the term quadrilateral is commonly used.
What are faces on a 3D shape?
Faces. A face is a flat or curved surface on a 3D shape. For example a cube has six faces, a cylinder has three and a sphere has just one.
What 3D shape has 4 rectangular faces?
A cuboid has 8 vertices. It has 4 around the top rectangular face and 4 around the bottom rectangular face. A cuboid has the same number of faces, edges and vertices as a cube. This is because a cube is a special type of cuboid that has all of its edges the same size.
What polyhedron has 4 faces?
tetrahedron
The smallest polyhedron is the tetrahedron with 4 triangular faces, 6 edges, and 4 vertices.
What is a 4 sided pyramid called?
In geometry, a tetrahedron (plural: tetrahedra or tetrahedrons), also known as a triangular pyramid, is a polyhedron composed of four triangular faces, six straight edges, and four vertex corners. The tetrahedron is the simplest of all the ordinary convex polyhedra and the only one that has fewer than 5 faces.
Can a cuboid have 4 square faces?
A cuboid has 6 flat faces. This cuboid has 2 square faces and 4 rectangular faces. An edge is the line where two faces touch.
What are 4 vertices?
A quadrilateral is a polygon that has exactly four sides. (This also means that a quadrilateral has exactly four vertices, and exactly four angles.)
What 3d object has 4 triangular faces?
What 3d shape has 4 faces and 5 vertices?

| Square-based pyramid | 5 | 5 |
| Triangular-based pyramid | 4 | 4 |
