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, and 2n edges. All pyramids are self-dual.

Web1 Answer. Sorted by: 1. Take z axis up, and the base of the pyramid aligned with the x and y axes. I think you mean that one side plane has a normal vector n = ( 0, cos ( 25 ∘), sin ( 25 ∘)), and an adjacent side plane has normal m = ( cos ( 25 ∘), 0, sin ( 25 ∘)). Then the cosine of the angle between the perpendiculars is the dot product. WebCalculating angle in a pyramid.
