Six - a pyramidic form with a triangular base is going to have three edges along the periphery of the base. There will be three planar surfaces that comprise the "upright" side surfaces, each of which will also be triangular in shape and sharing common edges with those triangular surfaces on either side. Visualize it by drawing an equilateral triangle on a sheet of paper. Next, bisect each interior angle of that triangle, stopping each bisector where it intersects with the other bisectors. Now count the line segments that extend from apex to apex and add to that number the line segments that extend from an apex to the bisector intersection. Total count is six line segments... thus six edges.

A triangular based pyramid is usually called a tetrahedron and it has 4 faces, 6 edges and 4 corners (usually called vertices)
A triangular base pyramid has 4 faces, 6 edges and 4 vertices
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 triangular pyramid has 4 faces 4 vertices and 6 edges.
There are 8 edges in a Square Based Pyramid!
