6 edges and 4 vertices
A triangular-based pyramid has six edges: three in the base triangle and three from there to the apex.
A pyramid with an n-sided base will have n + 1 vertices, n + 1 faces, and 2n edges. 6 edges
A triangle based pyramid has 6, a square based pyramid has 8.
The edges for a rectangular pyramid is 8.
