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.
