The term dodecahedron is 2+10 or 12 sided figure.
An octahedron has 12 edges and 8 faces.
Octogon
a triangle
A triangle has three faces. In geometry, a face refers to a flat surface of a solid shape. Since a triangle is a two-dimensional shape with three sides, it has three faces. Each side of the triangle forms one of its three faces.
A triangle has only one face and, not surprisingly, its shape is a triangle.
A tetrahedron has 4 faces, 6 edges, and 4 corners (or vertices). Each face is a triangle, and the shape is the simplest form of a polyhedron. The vertices are connected by edges, which define the triangular faces.
A regular dodecahedron, for example. Each face is a regular pentagon so no face has parallel sides. However, the edges on opposite faces are parallel to one another.
A cylinder has a circular face at each end, and a rectangular face folder around the middle. The only edges are the edges of the circular ends.
A tetrahedron has four triangular faces. It is a three-dimensional geometric shape with four vertices and six edges. Each face is an equilateral triangle in a regular tetrahedron.
A tetrahedron has four faces. Each face is a triangle, and the tetrahedron is a type of polyhedron that is the simplest three-dimensional shape. It also has four vertices and six edges.
a pyramid where each face is the shape of a triangle
A triangle has one face, three vertices and three edges.
Oh, dude, an equilateral triangle has 3 vertices, 3 faces (which are also the sides), and 3 edges. It's like the most balanced shape ever, so chill.
