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 cube. Vertices are corners and a cube has 8 corners. Faces are the flat surfaces on three dimensional shapes a cube has 6 faces.
A sphere. A sphere is a solid figure that has no faces, edges, or vertices. This is because it is completely round; it has no flat sides or corners.
It has a flat base, a curved surface area, a circular edge and one vertex.
An hemisphere is half of a globe with a circular flat base, a round edge, a curved surface but no vertices.
