Regular Star vs Straight Side Star - Geometric Shape Comparison #1896010 (License: Personal Use)

The left figure is a regular star (a concave pentagram with intersecting lines), while the right is a straight-side star (a convex pentagon with sharp outward points and no internal intersections). Both are five-pointed but differ in topology: the regular star has re-entrant angles, whereas the straight-side version maintains all interior angles less than 180°.
