9: the eight vertices of the octagon plus the vertex at the apex of the pyramid.
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 pyramid will have as many triangular faces as the number of sides its base has, plus one in the shape of its base. This means an octagon based pyramid has nine faces (eight triangular ones plus the octagon base).
9 vertices, because an octagon has 8 vertices and in a pyramid there is one on top, so 9. One
A triangular based pyramid has 4 vertices.
A square based pyramid has 5 vertices.
It depends on the configuration. Here are some: A nonagon-based pyramid will have 18 edges and 10 vertices; An octagon based prism will have 24 edges and 16 vertices; A pentagon-based dipyramid will have 15 edges and 7 vertices. There are others.
