What is the name of the star shape?

Regular star shape:

A regular star shape, also known as a regular star polygon, is a self-intersecting equilateral and equiangular polygon.

What is a 3D hexagon called?

3D solid shapes

For example, in the prism below, the cross section is a hexagon. This is called a hexagonal prism.

What is the 3D name for a oval?

ovoid
In common English, the term is used in a broader sense: any shape which reminds one of an egg. The three-dimensional version of an oval is called an ovoid.

How many types of star shapes are there?

There are seven main types of stars. In order of decreasing temperature, O, B, A, F, G, K, and M. O and B are uncommon, very hot and bright. M stars are more common, cooler and dim.

What is a 14 sided 3D shape called?

A tetradecahedron is a 14-sided polyhedron, sometimes called a tetrakaidecahedron.

Is a trapezoid a 3D shape?

The 3D figure of a trapezoid is called a trapezoidal prism since these are figures that have a length, width, and depth. The edges of the prism is where the faces meet, and the vertices of the prism are the corners where three or more surfaces meet.

What do you call a hexagonal prism?

In geometry, the hexagonal prism is a prism with hexagonal base. This polyhedron has 8 faces, 18 edges, and 12 vertices. Since it has 8 faces, it is an octahedron. However, the term octahedron is primarily used to refer to the regular octahedron, which has eight triangular faces.

Nonagon/Number of edges
In geometry, a nonagon (/ˈnɒnəɡɒn/) or enneagon (/ˈɛniəɡɒn/) is a nine-sided polygon or 9-gon. The name nonagon is a prefix hybrid formation, from Latin (nonus, “ninth” + gonon), used equivalently, attested already in the 16th century in French nonogone and in English from the 17th century.

What name is given for a shape with 10 sides?
