triangular pyramid
It is a polyhedron.
No, a triangle does not have three faces; it is a two-dimensional shape with three sides and three angles. In three-dimensional geometry, the term "face" refers to the flat surfaces of a solid object, such as a tetrahedron, which has four triangular faces. A triangle itself exists only in a plane and does not have any volume or faces like a three-dimensional shape.

A solid figure with 2 flat surfaces and 0 vertices is a cylinder. A cylinder has two circular flat surfaces, known as bases, and no vertices because it does not have any corners or points where edges meet. It is a three-dimensional shape that is formed by a curved surface connecting the two bases.
Like 3D. Looks like you can hold it. It's not flat
Polyhedron (plural polyhedra)
A polyhedron.
It is a polyhedron.
A face.
In geometry, a circle is a two-dimensional object, so it does not have a surface. Only three-dimensional objects have surfaces. A disc is a flat, circular three-dimensional object.

A three dimensional shape bounded by plane (flat) faces is a polyhedron.
Two. Considering this is a two-dimensional object, cut out of a piece of paper it would have two flat surfaces, the front and the back. If your talking a about a sphere, the three-dimensional object of a circle, it has no flat surfaces considering it is round.
