A pyramid is any three-dimensional structure where the upper surfaces are triangular and converge on one point.The base of pyramids are usually quadrilateral or trilateral but generally it can be any polygon shape),meaning that a pyramid usually has three or four sides but theoretically there is no limit to the number of sides a pyramid can generally have lots more sides.But all pyramids must have trilateral sides.The measurements of these triangles uniformly classify the shape as isosceles and sometimes equilateral.
A pyramid's design,with the majority of the weight closer to the ground,means that less material higher up on the pyramid will be pushing down from above.This allowed early civilizations to create stable monumental structures.For thousands of years,the largest structures on Earth were pyramids:first the Red Pyramid in the Dashur Necropolis and then the Great Pyramid of Khufu,the only remaining Wonder of the World.
