Are pyramids equilateral triangles?
Classical pyramids such as the structures at Giza have square bases and lateral sides close in form to equilateral triangles. When the closed curve becomes a circle one obtains a cone and this cone becomes a cylindrical rod when point P is moved to infinity.
What’s the difference between a pyramid and a triangle?
is that triangle is (geometry) a polygon with three sides and three angles while pyramid is an ancient massive construction with a square or rectangular base and four triangular sides meeting in an apex, such as those built as tombs in egypt or as bases for temples in mesoamerica.
Can a pyramid have 8 faces and 20 edges?
In geometry, a deltahedron (plural deltahedra) is a polyhedron whose faces are all equilateral triangles. There are infinitely many deltahedra, but of these only eight are convex, having 4, 6, 8, 10, 12, 14, 16 and 20 faces.
