  2. Star polygon - Wikipedia

    en.wikipedia.org/wiki/Star_polygon

    Polygrams include polygons like the pentagram, but also compound figures like the hexagram. One definition of a star polygon , used in turtle graphics , is a polygon having q ≥ 2 turns ( q is called the turning number or density ), like in spirolaterals .

  3. Star polyhedron - Wikipedia

    en.wikipedia.org/wiki/Star_polyhedron

    In geometry, a star polyhedron is a polyhedron which has some repetitive quality of nonconvexity giving it a star-like visual quality. There are two general kinds of star polyhedron: Polyhedra which self-intersect in a repetitive way. Concave polyhedra of a particular kind which alternate convex and concave or saddle vertices in a repetitive way.

  4. Star-shaped polygon - Wikipedia

    en.wikipedia.org/wiki/Star-shaped_polygon

    In geometry, a star-shaped polygon is a polygonal region in the plane that is a star domain, that is, a polygon that contains a point from which the entire polygon boundary is visible. Formally, a polygon P is star-shaped if there exists a point z such that for each point p of P the segment ⁠ z p ¯ {\displaystyle {\overline {zp}}} ⁠ lies ...

    Star polygon – there are multiple types of stars Pentagram - star polygon with 5 sides; Hexagram – star polygon with 6 sides Star of David (example) Heptagram – star polygon with 7 sides; Octagram – star polygon with 8 sides Star of Lakshmi (example) Enneagram - star polygon with 9 sides; Decagram - star polygon with 10 sides

  6. Pentagram - Wikipedia

    en.wikipedia.org/wiki/Pentagram

    The word pentagram refers to just the star and the word pentacle refers to the star within a circle, although there is some overlap in usage. [4] The word pentalpha is a 17th-century revival of a post-classical Greek name of the shape.

  7. Star domain - Wikipedia

    en.wikipedia.org/wiki/Star_domain

    A star domain (equivalently, a star-convex or star-shaped set) is not necessarily convex in the ordinary sense. An annulus is not a star domain.. In geometry, a set in the Euclidean space is called a star domain (or star-convex set, star-shaped set [1] or radially convex set) if there exists an such that for all , the line segment from to lies in .

    Enneagram, a nine-pointed star polygon; Decagram, a ten-pointed star polygon; Hendecagram, an eleven-pointed star polygon; Dodecagram, a twelve-pointed star polygon; Magic star, a star polygon in which numbers can be placed at each of the vertices and intersections, such that the four numbers on each line sum to the same "magic" constant
