The faces on the pyramid are called isosceles triangle. sorry, i don't know how to spell 'isosceles.
The fixed point at the intersection of all the faces of the pyramid is called the VERTEX of the pyramid.
They may be called lateral faces.
The flat surfaces on a pyramid (Geometry) are called faces. Therefore, a standard pyramid consists of four faces and a base (bottom).
It is an octagonal based pyramid.
A hexagonal pyramid.================A pyramid with 7 faces has a base plus 6 triangular sides, so is called a hexagonal pyramid.
A solid figure with five faces is called a pyramid. Specifically, a triangular pyramid, or tetrahedron, has four triangular faces, while a square pyramid has one square base and four triangular faces, totaling five. The pyramid's faces meet at a single point called the apex.
The flat surfaces on a pyramid are called faces. A pyramid has one base and triangular faces that meet at a single point called the apex. On a cube or rectangular prism, the flat surfaces are called faces as well. But unlike a pyramid, a cube has six square faces, while a rectangular prism has two rectangular bases and four rectangular faces.
That is called a tetrahedron.
base
"faces"
A pyramid with five faces is called a square pyramid. It consists of a square base and four triangular faces that converge at a single apex. The base has four edges, while the triangular faces connect each vertex of the base to the apex.
The height of the triangular face of a pyramid is called the slant height.
