Two...the triangles and the quadrilateral. That shape also has 5 faces just in case you wanted to know.
None.
A triangular pyramid has four triangular faces.
A pyramid with an n-sided base will have n + 1 vertices, n + 1 faces, and 2n edges. 5 faces, 8 edges, 5 vertices
The most common pyramid shapes have 3 faces on a triangular base or 4 faces on a square face. Other pyramid shapes may have more faces corresponding to the shape of the base.
6 faces
five
5
a pyramid has for faces and a base so all in all 5 faces the four on the outside are triangular and the base is square :)
Two. Triangles and a square
Just one: a tetrahedron or triangular pyramid.
A pyramid is a generic term and can have any number (>3) of plane faces. A triangular pyramid has 4 faces, a rectangular one has 5, and so on. A pyramid whose base has n sides has n+1 faces.
