There are no curved edges on a triangular pyramid.
A pyramid has a combination of flat and curved surfaces, but it typically consists of flat surfaces only. Specifically, a pyramid has a base that is a polygon (flat surface) and triangular faces that connect the base to a single apex, all of which are flat. Therefore, a standard pyramid has no curved surfaces. The total number of surfaces depends on the number of sides of the base polygon; for example, a square pyramid has five flat surfaces (one base and four triangular faces).
A triangular prism contains zero curved and 5 flat surfaces.

A triangular based prisim has four faces.
A pyramid has a total of ( n + 1 ) plane surfaces, where ( n ) is the number of triangular faces. For example, a square pyramid has a square base (1 surface) and four triangular faces, resulting in a total of 5 plane surfaces. The specific number can vary depending on the shape of the base; for instance, a triangular pyramid (tetrahedron) has 4 surfaces in total.
