Which of these two polyhedrons is concave? Note that the interior dihedral angle formed by the planes containing ∆EJF and ∆KJF is larger than 180 ° . To determine

To find:

The concave polyhedron.

Explanation

Approach:

1) A polygon is a two dimensional shape form with more than two straight lines.

2) A polyhedron is a three-dimensional shape made up of polygons as sides.

3) Each flat surface of a polyhedron is a polygon and is called a face. A polyhedron must have at least four faces.

4) The line segment where two faces of a polyhedron meet is called an edge.

5) The point where three or more edges of a polyhedron meet is called a vertex.

6) A dihedral angle is the angle between two faces with a common edge.

7) A polyhedron has dihedral angles between each of their sides because each side

of a polyhedron is a plane.

8) When a polyhedron is convex, each face determines a plane for which all remaining faces lie on same side of that plane...
