A nonagon is nine sided. So, the base would have 9 sides and each face would be triangle.
18 edges would be my answer.

A pyramid with 18 edges would be called a nonagonal pyramid. A prism with 18 edges is called a hexagonal prism.
There are 10 sides : 9 sides and the nonagonal base.
Edges: 27 Faces: 11 Vertices: 18
Base has 9 vertexes and then the point at the top makes 10.
16 edges- the edges of the base, and the edges leading to the point of the pyramid.

There are many possibilities. A nonagonal pyramid A hexagonal prism A hexagonal dipyramid are three.

10. For any pyramid, it will be one more than the number of vertices in the base.
a pyramid has 8 edges
A nonagonal prism.
Base has 9 vertexes and then the point at the top makes 10.
8 edges * * * * * Not necessarily. A triangular pyramid has 6 edges. A heptagonal pyramid had 14 edges and so on.
