Question

define non convex polyhedrons ​

Answer 1

Answer:

A polygon is convex if all the interior angles are less than 180 degrees. If one or more of the interior angles is more than 180 degrees the polygon is non-convex (or concave).

Answer 2

Answer:

CONVEX POLYHEDRON ;- A a convex polyhedron can be defined as a polyhedron for which a line connecting any two (noncoplanar) points on the surface always lies in the interior of the polyhedron.

NON - CONVEX POLYHEDRON ;- In mathematics, a Nonconvex polyhedron is a polyhedron that is not convex.
