A triangular based pyramid has 4 vertices, 6 edges and 4 faces
There are four vertices in a square-base pyramid. * * * * * Actually. a square based pyramid has four vertices at its base and a fifth vertex where the triangular sides of the pyramid meet. So, 5 vertices in all.
A pentagonal based pyramid has 6 faces, ten edges and 6 vertices.
A rectangular based pyramid has 5 vertices, 8 edges and 5 faces
That will depend on its base because if it is square based then it will have 5 vertices but if it is triangular based then it will have 4 vertices
