## What shape has 8 faces all equilateral triangles?

octahedron

## Which solid have all faces are equilateral triangles?

deltahedron

## What 3D shape has 6 faces and 8 vertices?

cube

## What’s a 3 sided pyramid called?

tetrahedron

## What is a pyramid with 5 faces called?

In geometry, a pentagonal pyramid is a pyramid with a pentagonal base upon which are erected five triangular faces that meet at a point (the vertex).

## What are planes on a pyramid?

It is only as thick as a point, which takes up no space at all. So a plane is like an imaginary sheet of paper, infinitely wide and long, but with no thickness. When we talk about a triangle or a square, these shapes are like pieces cut out of a plane, as if you had cut them out of a piece of paper.

## What exactly is a pyramid scheme?

A pyramid scheme is a fraudulent system of making money based on recruiting an ever-increasing number of “investors.” The initial promoters recruit investors, who in turn recruit more investors, and so on.

## What is Pyramid math?

In geometry, a pyramid is a polyhedron formed by connecting a polygonal base and a point, called the apex. Each base edge and apex form a triangle, called a lateral face. It is a conic solid with polygonal base. A triangle-based pyramid is more often called a tetrahedron.

## What is a pyramid math is fun?

A solid object where: • The sides are triangles which meet at the top (the apex). • The base is a polygon (a flat shape with straight sides) This is a square pyramid, but there are also triangular pyramids, pentagonal pyramids, and so on.

## What do all pyramids have in common math?

All pyramids are named upon the shape of their base, which is always a polygon (such as a square, triangle, rectangle, pentagon, etc.) Though pyramids may have different bases, they have one thing in common: all of the lateral faces of pyramids are “triangular” in shape.
