What is the mathamatical definition of concave and convex polyhedra?
Annie
There is a good way to know if a polyhedra is convex. If you place the shape inside a sphere and all of the vertexes were touching the edge of the sphere, then it would be convex. If all of the vertexes didn't touch the edge, then it would be concave. How simply is that?
