Which shape has a triangle for a face?
In geometry, a deltahedron (plural deltahedra) is a polyhedron whose faces are all equilateral triangles.
Which shape has exactly 4 triangular faces?
tetrahedron
The smallest polyhedron is the tetrahedron with 4 triangular faces, 6 edges, and 4 vertices.
What is a shape with 8 triangular faces?
octahedron
What is an octahedron? Octahedra have: 8 triangular faces. 12 edges.
What 3D shape has 2 triangular faces?
A triangular prism has 2 triangular faces and 3 rectangular faces.
What 3D shape has triangular sides?
A triangular prism is a 3D polyhedron, made up of two triangular bases and three rectangular sides. The shape is made up of 2 congruent bases, 3 congruent lateral faces, 9 edges, and 6 vertices. The bases are shaped as a triangle and the sides or faces are shaped like a rectangle.
What is an example of a triangular pyramid?
They have 6 edges, 3 are along the base and 3 are extending up from the base. When six edges are of the same length, all the triangles are equilateral, and the pyramid would be called the regular tetrahedron. A Rubik’s triangle is an example of a triangular pyramid.
How many polyhedra are there?
five regular polyhedra
Also known as the five regular polyhedra, they consist of the tetrahedron (or pyramid), cube, octahedron, dodecahedron, and icosahedron. Pythagoras (c. 580–c. 500 bc) probably knew the tetrahedron, cube, and dodecahedron.
Does a dodecahedron have?
All the faces are flat 2-D shapes. There are five platonic solids and dodecahedron is one of them. Platonic solids are convex polyhedra in which the faces are made up of congruent regular polygons with the same number of faces meeting at each of their vertices….Dodecahedron.

How many triangular faces does a cube have?
6 faces
A cube, just like a rectangular prism, has 6 faces (all squares), 8 vertices, and 12 edges. A triangular prism has five faces. Its base is a triangle. (Notice that even when the triangular prism sits on a rectangle, the base is still a triangle.)
Which solid has only triangular faces?
TRIANGULAR PYRAMIDS are solids which is made of only triangular faces.
How do you determine your face shape?
There are several methods to determining the shape of your face. A popular way, often touted in beauty magazines, is the lipstick method. Standing in front of a mirror that you can see your whole head in, use a tube of lipstick to trace the outline of your face on the mirror.
How do you measure face shape?
Using a tape measure, record the distance between your cheekbones, between the widest points of your jaw line, across your forehead at the widest point, and from hairline to chin. These proportional measurements may give you a good idea of what shape category your face fits.
What has one square face and four triangle faces?
A square-based pyramid has one square face on its base and four triangular faces. A square has four sides and so the square base has a triangle attached to each edge.
What is a triangular face?
Triangular face. Jump to navigation Jump to search. A triangular face, in the simplest sense, is a face whose lower half becomes relatively thin, approaching an appearance of a triangle with a tip facing downwards. It is not necessarily caused by any disease, but is common in individuals with osteogenesis imperfecta.
