A new tiling shape may lead to developments in biochemistry, architecture, materials engineering, and more. With an infinite number of irregular pentagon forms, there could be an infinite number ...

but it’s easy to construct an irregular, convex pentagon that does not admit an edge-to-edge monohedral tiling of the plane. For example, consider the pentagon below, whose interior angles measure 100 ...

Constructing an irregular pentagon in this way shows us why not all irregular pentagons can tile the plane: There are certain restrictions on the angles that not all pentagons satisfy. But even ...

Another spiral tiling was published 1985 by Michael D. Hirschhorn and D.C. Hunt using an irregular pentagon (shown on the right). Robert Coolman, PhD, is a teacher and a freelance science writer ...

They can’t fit around corners,” he said. It’s possible to tile an irregular pentagon, however. It’s just not easy to figure out the correct pattern. It also cannot be proven how many ...

The Pentagon defines irregular warfare as a "campaign to assure or coerce states or other groups through indirect, non-attributable, or asymmetric activities." What this means, in effect ...

Casey Mann and Jennifer McCloud-Mann with help from David Von Derau discovered a pattern of tiling convex irregular pentagons. It is only the 15th pentagon tiling pattern ever discovered.
