The answer is this solid figure is a nonagonal prism with 11 faces.

## How many edges does a Nonagon pyramid have?

Nonagon

Regular enneagon (nonagon)
Edges and vertices 9
Schläfli symbol {9}
Coxeter–Dynkin diagrams
Symmetry group Dihedral (D9), order 2×9

How many vertices does a nonagonal pyramid have?

To be a pyramid with 10 vertices, you must have a nonagonal pyramid, with 9 vertices around the base, and the tenth at the apex.

### What is a pyramid with 9 faces?

In geometry, an enneahedron (or nonahedron) is a polyhedron with nine faces.

### What pyramid has 11 faces?

Dual polyhedron The dual of the gyroelongated pentagonal pyramid has 11 faces: 5 kites, 1 regular pentagonal and 5 irregular pentagons.

What is a nine sided pyramid called?

octagonal pyramid
An octagonal pyramid is a pyramid that has a bottom that’s the shape of an octagon and has triangles as sides. These types of pyramids have nine sides all together, called faces.

## What type of pyramid has 9 faces?

Dual polyhedron The dual of the elongated square pyramid has 9 faces: 4 triangular, 1 square and 4 trapezoidal.

## What type of pyramid has 9 vertices?

An octagonal pyramid has nine vertices; eight are located where the triangular faces meet the base and the ninth is the point at which all of the triangular faces meet at the top of the pyramid. We often call the vertex on top the apex of the pyramid.

What pyramid has 7 vertices?

hexagonal-based pyramid
2) The hexagonal-based pyramid has 7 vertices, the pentagonal prism has 10 vertices and the cuboid has 8 vertices.

### What 3D object has 9 vertices 16 edges and 9 faces?

hexagonal pyramid and the pentagonal prism.

### Are the pyramids 8 sided?

The base of the Great Pyramid of Giza is a square, right? Well, not quite. Despite what you may think about this ancient structure, the Great Pyramid is an eight-sided figure, not a four-sided figure. Each of the pyramid’s four side are evenly split from base to tip by very subtle concave indentations.

What pyramid has 16 edges?

Elongated square pyramid

Elongated square pyramid
Edges 16
Vertices 9
Vertex configuration 4(43) 1(34) 4(32.42)
Symmetry group C4v, [4], (*44)

## Do pyramids have 8 sides?

Despite what you may think about this ancient structure, the Great Pyramid is an eight-sided figure, not a four-sided figure. Each of the pyramid’s four side are evenly split from base to tip by very subtle concave indentations. It is believed that this discovery was made in 1940 by a British Air Force pilot named P.

## What are the 4 types of pyramids?

Based on the shape of the base of the pyramid, the pyramid is classified as a triangular pyramid, square pyramid, pentagonal pyramid, and so on.

Are there any 3 sided pyramids?

The Egyptian pyramids actually have four triangle-shaped sides, whereas a three-sided pyramid shape is called a tetrahedron. The proper name for a three-sided pyramid is a tetrahedron. Tetrahedrons have three showing sides formed by three triangles of equal dimensions.

### What prism has 9 vertices?

triangular prism
A triangular prism is polyhedron and a three-dimensional shape that has 5 faces, 6 edges and 9 vertices. Its bases are triangular and sides are rectangular.

### What 3D shape has 9 edges?

A triangular prism has 5 faces (2 triangular faces, 3 rectangular faces), 9 edges, 6 vertices, and slides and stacks.

What polyhedron has 9 faces 9 vertices and 16 edges?

Elongated square pyramid
Type Johnson J7 – J8 – J9
Faces 4 triangles 1+4 squares
Edges 16
Vertices 9

## What is a prism with 9 edges?

Answer: The shape which has 6 vertices, 9 edges and 5 faces is called a Triangular prism.

## What 3d shape has 9 edges?

A triangular prism has 9 edges.

What is the shape of a right nonagonal pyramid with hidden edges?

Illustration of a right nonagonal pyramid with hidden edges shown. The base is a nonagon and the faces are isosceles triangles.

### What are nonagons In geometry?

Nonagons are rarely used in most geometry texts, but it is an intriguing shape, whether you examine a regular nonagon or an irregular nonagon. To be a nonagon or enneagon, the shape must have all these properties: The nine line segments are the nonagons’ sides, and they connect to form the nonagons’ angles.

### Can a nonagon be constructed with a compass?

Although a regular nonagon is not constructible with compass and straightedge (as 9 = 3 2, which is not a product of distinct Fermat primes ), there are very old methods of construction that produce very close approximations. It can be also constructed using neusis, or by allowing the use of an angle trisector . Symmetries of a regular enneagon.

How do you know if a nonagon is an irregular shape?

Irregular nonagons can have sides of different lengths and interior angles of varying sizes. Yet, even odd shapes like these are nonagons: A polygon with at least one interior angle greater than 180° 180 ° is a concave polygon and always created an irregular polygon. A self-intersecting nonagon is a complex nonagon.
