  2. Equiangular polygon - Wikipedia

    en.wikipedia.org/wiki/Equiangular_polygon

    An equiangular hexagon with 1:2 edge length ratios, with equilateral triangles. [6] This is spirolateral 2 120°. Direct equiangular hexagons, <6> and <6/2>, have 120° and 60° internal angles respectively. 120° internal angles of an equiangular hexagon, <6> An equiangular hexagon with integer side lengths may be tiled by unit equilateral ...

  3. Regular polygon - Wikipedia

    en.wikipedia.org/wiki/Regular_polygon

    A non-convex regular polygon is a regular star polygon. The most common example is the pentagram, which has the same vertices as a pentagon, but connects alternating vertices. For an n-sided star polygon, the Schläfli symbol is modified to indicate the density or "starriness" m of the polygon, as {n/m}.

  4. Icositetragon - Wikipedia

    en.wikipedia.org/wiki/Icositetragon

    There are 7 subgroup dihedral symmetries: (Dih 12, Dih 6, Dih 3), and (Dih 8, Dih 4, Dih 2 Dih 1), and 8 cyclic group symmetries: (Z 24, Z 12, Z 6, Z 3), and (Z 8, Z 4, Z 2, Z 1). These 16 symmetries can be seen in 22 distinct symmetries on the icositetragon. John Conway labels these by a letter and group order. [2]

  5. Hexagon - Wikipedia

    en.wikipedia.org/wiki/Hexagon

    A principal diagonal of a hexagon is a diagonal which divides the hexagon into quadrilaterals. In any convex equilateral hexagon (one with all sides equal) with common side a, there exists [11]: p.184, #286.3 a principal diagonal d 1 such that and a principal diagonal d 2 such that

  6. Ex-tangential quadrilateral - Wikipedia

    en.wikipedia.org/wiki/Ex-tangential_quadrilateral

    In Euclidean geometry, an ex-tangential quadrilateral is a convex quadrilateral where the extensions of all four sides are tangent to a circle outside the quadrilateral. [1] It has also been called an exscriptible quadrilateral. [2] The circle is called its excircle, its radius the exradius and its center the excenter (E in the figure). The ...

  7. Convex polygon - Wikipedia

    en.wikipedia.org/wiki/Convex_polygon

    The polygon is the convex hull of its edges. Additional properties of convex polygons include: The intersection of two convex polygons is a convex polygon. A convex polygon may be triangulated in linear time through a fan triangulation, consisting in adding diagonals from one vertex to all other vertices.

  9. Bicentric quadrilateral - Wikipedia

    en.wikipedia.org/wiki/Bicentric_quadrilateral

    The area of a bicentric quadrilateral can be expressed in terms of two opposite sides and the angle θ between the diagonals according to [9] K = a c tan ⁡ θ 2 = b d cot ⁡ θ 2 . {\displaystyle K=ac\tan {\frac {\theta }{2}}=bd\cot {\frac {\theta }{2}}.}
