What shapes comprise the interior space of a pentagram?
Answer
A central pentagon plus five exterior triangles.
The visual complexity and geometric structure of the pentagram are defined by its internal composition. When the five intersecting lines that form the star polygon are drawn, they inherently define two distinct types of internal regions. At the very center of the figure, where all lines cross, a smaller, inverted regular pentagon is formed. Surrounding this central shape are five distinct triangular regions that point outward toward the five main vertices of the star. This arrangement—a central pentagon enclosed by five surrounding triangles—is a key structural feature that differentiates it geometrically from the simple, single interior region possessed by a standard convex pentagon.
