In 2 dimensions, a heptagon.
In 3 dimensions a hexagonal pyramid, a pentagonal dipyramid and some other exotic shapes - eg shape with one triangular base and one quadrilateral base and miscellaneous faces joining them.
Heptagon
Heptagonal pyramid * * * * * No. A heptagonal pyramid has 8 vertices. You need a hexagonal pyramid or a pentagonal dipyramid for 7 vertices. Or, in 2d, a heptagon.
The shape that has no vertices and is round is a circle. The circle is the only shape that does not have vertices.
no shape equals to that
A pentagonal prism has 7 faces, 15 edges and 10 vertices
a shape with 7 vertices
Heptagon
A shape with 7 sides.
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.
Heptagon
A 3D shape with 7 vertices and 7 edges is a triangular prism. It consists of two triangular bases connected by three rectangular faces. The triangular bases contribute 3 vertices each, while the three additional vertices are created by connecting the two bases, resulting in a total of 7 vertices and 7 edges.
