👉 In geometry, a holohedron is a polygonal shape that has no edges or vertices but instead has its points as vertices. It can be defined in terms of a three-dimensional space and it's also called a spherical polygon. The definition of a spherical polygon in this context means that it is made up of all the points on a sphere, with each point being connected to every other point by an edge. This means that there are no edges or vertices, making the shape a spherical polygon
