In geometry, a tetrahedron (plural: tetrahedra or tetrahedrons), also known as a triangular pyramid, is a polyhedron composed of four triangular faces, six straight edges, and four vertex corners.
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.
Beside this, Are there 3 sided pyramids?
A “three sided pyramid” is called a tetrahedron.
Likewise, How many sides does a regular pyramid have?
4
Also, Can a pyramid have 5 sides?
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). Like any pyramid, it is self-dual. The regular pentagonal pyramid has a base that is a regular pentagon and lateral faces that are equilateral triangles.
What is a 3 sided pyramid called?
In the case of a tetrahedron the base is a triangle (any of the four faces can be considered the base), so a tetrahedron is also known as a “triangular pyramid”.

What is the difference between step pyramids and true pyramids?
It is known as a Step-Pyramid as it does not have a true pyramid shape but rises to the top in five giant steps (see the people to the left of the pyramid to give you an idea of how large it is). The step pyramid is basically five Mastabas – one on top of the other, with each one getting smaller as you near the top.

What is a pyramid with 8 sides called?
An octagonal pyramid is a pyramid with a base that’s a polygon with eight sides, or an octagon, and triangular faces, or sides, that meet at a point directly above the bottom. The points at which the edges of the base and sides meet are called the vertices of the pyramid.
