If all faces are congruent, the tetrahedron is known as an isosceles tetrahedron. If all faces are congruent to an equilateral triangle, then the tetrahedron is known as a regular tetrahedron (although the term "tetrahedron" without further qualification is often used to mean "regular tetrahedron"). A …
WebPolyhedron Definition. A three-dimensional shape with flat polygonal faces, straight edges, and sharp corners or vertices is called a polyhedron. Common examples are cubes, prisms, pyramids. However, cones, and … WebA hexagonal prism is a 3D-shaped figure with the top and bottom shaped like a hexagon. It is a polyhedron with 8 faces, 18 edges, and 12 vertices where out of the 8 faces, 6 faces are in the shape of rectangles and 2 faces are in the shape of hexagons. Some of the real-life examples of a hexagon prism are pencils, boxes, nuts, etc.
WebThe faces of non-convex polyhedra can either be convex polygons, star-polygons (like the pentagram), or skew polygons (which don't lie in a plane.) "Star-polyhedra" are a particular type of non-convex polyhedra. Things like balls and tori are not polyhedra. Those are called surfaces of nonzero genus. (The genus is the number of holes.) $\endgroup$
