In 2 dimensional space: a heptagon
In 3 dimensional space: a heptahedron.
A polygon with 9 vertices is a nonagon.
a shape with 7 vertices
Vertices are the points on any shape. For example, A 2-dimentional square has 4 vertices.
Heptagon
A shape with 7 sides.
It is a triangle inside another shape, usually such that its vertices are on the boundaries of the other shape.
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.
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').
pyrimid
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
