# How many faces are in a cone?

A cone has

**one face**. It is a three-dimensional shape with a circular base, one side and one vertex. Faces can be identified as the flat surfaces on a three-dimensional figure.A.

### How many faces are on a sphere?

All of these figures are curved in some way, so they have no edges or vertices. What about their faces? A sphere has no faces, a cone has one circular face, and a cylinder has

**two**circular faces. Therefore, the number of faces increases by one from one figure to the next.#### How many edges does a triangle have?

A triangle is a polygon with**three edges**and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted .#### How many edges and vertices does a cylinder have?

2 edges#### What is an edge in math?

An**edge**is a line segment that joins two vertices (on the boundary or where faces meet). Example: This tetrahedron has 6**edges**. Vertices,**Edges**and Faces.

B.

### How many curved edges does a sphere have?

An edge is where 2 faces meet, again some can be straight, some can be curved e.g. a cube has 12 straight edges whereas a cylinder has

**2 curved edges**. A corner is where**3 edges**meet. A cube has 8 corners, as does a cuboid. A sphere has no edges and therefore no corners.#### How many sides are there in a pyramid shape?

The simplest regular pyramid then is a 4-sided pyramid (base +**3 sides**). Its proper name is a "tetrahedron". The tetrahedron has the extra interesting property of having all**four**triangular sides congruent. An Egyptian pyramid has a square base and**four**triangular sides.#### How many corners and sides does a pentagon have?

A cyclic pentagon is one for which a circle called the circumcircle goes through all**five vertices**. The regular pentagon is an example of a cyclic pentagon.#### How many flat surfaces does a cone?

A**cone has**one face. It is a three-dimensional shape with a circular base, one side and one vertex. Faces can be identified as the**flat surfaces**on a three-dimensional figure.

C.

### How many faces has a cylinder?

#### How many faces has a sphere?

All of these figures are curved in some way, so they have no edges or vertices. What about their faces? A sphere has no faces, a cone has one circular face, and a cylinder has**two**circular faces. Therefore, the number of faces increases by one from one figure to the next.#### How many faces are on a triangular pyramid?

It has**4 Faces**. The 3 Side Faces are Triangles. The Base is also a Triangle. It has 4 Vertices (corner points)#### What is a flat shape?

A closed, two-dimensional or**flat**figure is called a plane**shape**. Different plane**shapes**have different attributes, such as the numbers of sides or corners. A side is a straight line that makes part of the**shape**, and a corner is where two sides meet.
