A triangular based pyramid has 4 flat faces, 6 edges and 4 vertices.
4
a pyramid with a triangular base has 4 faces. a pyramid with a square base has 5 faces.
A triangular pyramid is one with a triangle shaped base and triangular sides (4 sides, all of them identical), therefore it would only have 6 edges and 4 vertices There are eight edges in a triangular pyramid, and there are five vertices on a triangular pyramid. Edges are the places where two flat surfaces meet. Vertices are the places where three or more flat surfaces meet. * * * * * The sides of a triangular pyramid need not be identical.
4 triangle surfaces
not a pyramid!! well a triangular won't but still pyramids have 4 flat surfaces.
triangular pyramid
A square base, and four triangular shaped sides equals five flat surfaces.
There are five faces in a triangular pyramid. Gosh person, use your math book! Sorry you are wrong. It depends on the base if it is a square it has 5 surfaces if the base is a triangle it has 4 surfaces. So you must examine your pyramid carefully so as not to make a simple mistake.
