if you need to know how many triangles are in a polygon ... just take the number of its sides and subtract for example. nonagon has 9 sides so it will be 9-2=7 so, a nonagon has 7 triangles
Faces- 20 Edges- 30 Vertices- 12
It has 8 faces, 6 Vertices, and 12 edges * * * * * That is one configuration. An octahedron can also be a heptagonal pyramid which has 8 faces, 8 vertices and 14 edges.
it ha 6 faces 12 edges 8 (corners)
Pretty simple really: Vertices are corners and edges are boundaries so, a hexagon has six of each.

11
A nonagon is a 2-dimensional figure and so has only one face.
45
A nonagon is a plane (2-dimensional) figure.Faces . . . 1Edges . . . 0Vertices. . 9Sides. . . . 9
Nine faces. That's because the "hedron" part is for a polyhedron (3D shape). Then non is nine (think nonagon).
It is called a Nonagon.
Nonagon
A nonagon (9 sides) for example.
Triangle Pentagon Septagon Nonagon Etc
There are 9 vertices in a nonagon.
A Nonagon has 9 sides
