A triangular based pyramid has 4 flat faces, 6 edges and 4 vertices.
a cone has one flat surface one vertex and no edge.
Pyramid
A quadrilateral based pyramid.
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.
A pyramid with an n-sided base will have n + 1 vertices, n + 1 faces, and 2n edges.
a pyramid with a triangular base has 4 faces. a pyramid with a square base has 5 faces.
A tetrahedron is a triangular based pyramid that has 4 faces, 6 edges and 4 vertices.
A triangular based pyramid would fit the given description.
The flat surfaces on a pyramid (Geometry) are called faces. Therefore, a standard pyramid consists of four faces and a base (bottom).
