Enneagonal prism

Index Enneagonal prism

In geometry, the enneagonal prism (or nonagonal prism) is the seventh in an infinite set of prisms, formed by square sides and two regular enneagon caps. [1]

Geometry

Geometry (from the γεωμετρία; geo- "earth", -metron "measurement") is a branch of mathematics concerned with questions of shape, size, relative position of figures, and the properties of space.

Nonagon

In geometry, a nonagon or enneagon is a nine-sided polygon or 9-gon.

Prism (geometry)

In geometry, a prism is a polyhedron comprising an n-sided polygonal base, a second base which is a translated copy (rigidly moved without rotation) of the first, and n other faces (necessarily all parallelograms) joining corresponding sides of the two bases.

Semiregular polyhedron

The term semiregular polyhedron (or semiregular polytope) is used variously by different authors.

Square

In geometry, a square is a regular quadrilateral, which means that it has four equal sides and four equal angles (90-degree angles, or (100-gradian angles or right angles). It can also be defined as a rectangle in which two adjacent sides have equal length. A square with vertices ABCD would be denoted.

Uniform polyhedron

A uniform polyhedron is a polyhedron which has regular polygons as faces and is vertex-transitive (transitive on its vertices, isogonal, i.e. there is an isometry mapping any vertex onto any other).
