a square pyramid has 5 a circular pyramid has none
None. All faces on a pyramid are flat.
If you mean a tetrahedron then it is a triangular based pyramid with 4 flat faces
It has 5 flat faces because there are 4 flat faces at the top and 1 flat face at the bottom.
A pyramid can have 4 or more faces. A pyramid, with a n-sided polygon as base will have n+1 faces. The polygon with the least number of sides is a triangle and a triangular pyramid (tetrahedron) has 4 faces. A square based pyramid has 5 faces, and so on.
a pyramid with a triangular base has 4 faces. a pyramid with a square base has 5 faces.
A pyramid normally has flat faces
it has 0 curved faces
NO such object as a 'triangular pyramid'. This object is named a 'TETRAHEDRON'. The word 'tetrahedron' ,from classical languages, means 'tetra/four(4)' and 'hedron/solid object'. A tetrahedron has four(4) triangular faces. A pyramid has four(4) triangular faces, and a square base, making for five(5) faces. It is erroneously named ' a square pyramid', but there is no0 such thing.
The flat surfaces on a pyramid (Geometry) are called faces. Therefore, a standard pyramid consists of four faces and a base (bottom).
a pyramid with a triangular base has 4 faces. a pyramid with a square base has 5 faces.
"faces"
A pyramid has 4 flat faces, all of which are triangular. Don't confuse this with a square-based pyramid like those in Egypt, as they have 5 faces.
