In geometry, a pyramid (from Ancient Greek πυραμίς (puramís)) 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 pyramid with an n-sided base has n + 1 vertices, n + 1 faces, … See more A right pyramid with a regular base has isosceles triangle sides, with symmetry is Cnv or [1,n], with order 2n. It can be given an extended Schläfli symbol ( ) ∨ {n}, representing a point, ( ), joined (orthogonally offset) … See more The volume of a pyramid (also any cone) is $${\textstyle V={\tfrac {1}{3}}bh}$$, where b is the area of the base and h the height from the base to the … See more The centroid of a pyramid is located on the line segment that connects the apex to the centroid of the base. For a solid pyramid, the centroid is 1/4 the distance from the base to the apex. See more • Bipyramid • Cone (geometry) • Trigonal pyramid (chemistry) • Frustum See more A right pyramid can be named as ( )∨P, where ( ) is the apex point, ∨ is a join operator, and P is a base polygon. An isosceles triangle right tetrahedron can be written as ( )∨[( )∨{ }] as the join of a point to an isosceles triangle base, as [( )∨( )]∨{ } or { }∨{ } as the … See more The surface area of a pyramid is $${\textstyle SA=B+{\tfrac {1}{2}}PL}$$, where B is the base area, P is the base perimeter, and the slant height See more A 2-dimensional pyramid is a triangle, formed by a base edge connected to a noncolinear point called an apex.
