A nonagon is a two dimensional; figure with 9 vertices.
6
it has 5 verticles
8
A pentagon.
No 3D shape with FLAT SIDES has exactly 3 faces. 4 is the minimum.
i belive you ment vertices not verticles the shape with 4 sides and 4 vertices is a tetrahedral
A triangular prism
A circle
6
a square bottomed pyramid
a circle
A 4 sided shape has 4 vertices whereas a 3 sided shape has 3 vertices.
it has 5 verticles
according to my subject the answer is five(5) verticles
If you mean how many vertices are on an octagonal based pyramid then it has 9 vertices.
It is a cube or a cuboid that has 8 vertices, 12 edges and 6 faces
Polygons of 6 or more sides have more than 5 vertices such as an octagon which has 8 vertices
