In 2 dimensional space: a heptagon
In 3 dimensional space: a heptahedron.
a shape with 7 vertices
A polygon with 9 vertices is a nonagon.
Vertices are the points on any shape. For example, A 2-dimentional square has 4 vertices.
Heptagon
A shape with 7 sides.
Heptagon
The number of vertices does not determine the number of faces. If the shape with 6 vertices was a quadrilateral based bipyramid, it would have 8 faces. A hexagonal based pyramid has 7 vertices and 7 faces. So more vertices does not necessarily imply more faces.
It is a triangle inside another shape, usually such that its vertices are on the boundaries of the other shape.

Vertices are on a shape when two sides meet up and create a corner. For example, a square has 4 vertices, a tringle has 3 vertices, a circle has no vertices. (singular is 'vertex').
Vertices are the corners in a shape. Lets start with a triangle, It has 3 sides and 3 vertices's. I hope this answers your question Jordan McNeill
