1. The uniform star polyhedra have regular faces or regular star polygon faces.
2. Star forms have either regular star polygon faces or vertex figures or both.
3. Regular star polygons were first studied systematically by Thomas Bradwardine, and later Kepler.
4. The dual uniform star polyhedra have regular faces or regular star polygon vertex figures.
5. Some retrograde star antiprisms with regular star polygon bases cannot be constructed with equal edge lengths, so are not uniform polyhedra.
6. It's difficult to find regular star polygons in a sentence. 用regular star polygons造句挺難的
7. Only the "'regular star polygons "'have been studied in any depth; star polygons in general appear not to have been formally defined.
8. Branko Gr黱baum identified two primary definitions used by Kepler, one being the regular star polygons with intersecting edges that don't generate new vertices, and the second being simple isotoxal concave polygons.

10. In geometry, the { 7 / 2 } "'heptagrammic prism "'is one of an infinite set of nonconvex prisms formed by square sides and two regular star polygon caps, in this case two { 7 / 2 } heptagrams.
11. The linear truncation process can be generalized by allowing parametric truncations that are negative, or that go beyond the midpoint of the edges, causing self-intersecting star polyhedra, and can parametrically relate to some of the regular star polygons and uniform star polyhedra.
