    As a corollary of the annulus chord formula, the area bounded by the circumcircle ... For a regular polygon with 10,000 sides ... Regular polygon: Triangle: Square: p ...

  3. Square - Wikipedia

    en.wikipedia.org/wiki/Square

    In terms of the inradius r, the area of the square is =; hence the area of the inscribed circle is / of that of the square. Because it is a regular polygon, a square is the quadrilateral of least perimeter enclosing a given area. Dually, a square is the quadrilateral containing the largest area within a given perimeter. [6]

  4. Polygon - Wikipedia

    en.wikipedia.org/wiki/Polygon

    In either case, the area formula is correct in absolute value. This is commonly called the shoelace formula or surveyor's formula. [6] The area A of a simple polygon can also be computed if the lengths of the sides, a 1, a 2, ..., a n and the exterior angles, θ 1, θ 2, ..., θ n are known, from:

  5. Area - Wikipedia

    en.wikipedia.org/wiki/Area

    That is, the area of the rectangle is the length multiplied by the width. As a special case, as l = w in the case of a square, the area of a square with side length s is given by the formula: [1] [2] A = s 2 (square). The formula for the area of a rectangle follows directly from the basic properties of area, and is sometimes taken as a ...

  6. List of polygons - Wikipedia

    en.wikipedia.org/wiki/List_of_polygons

    Individual polygons are named (and sometimes classified) according to the number of sides, combining a Greek-derived numerical prefix with the suffix -gon, e.g. pentagon, dodecagon. The triangle , quadrilateral and nonagon are exceptions, although the regular forms trigon , tetragon , and enneagon are sometimes encountered as well.

  7. Constructible polygon - Wikipedia

    en.wikipedia.org/wiki/Constructible_polygon

    A regular polygon with n sides can be constructed with ruler, compass, and angle trisector if and only if =, where r, s, k ≥ 0 and where the p i are distinct Pierpont primes greater than 3 (primes of the form +). [8]: Thm. 2 These polygons are exactly the regular polygons that can be constructed with Conic section, and the regular polygons ...

    Apothem of a hexagon Graphs of side, s; apothem, a; and area, A of regular polygons of n sides and circumradius 1, with the base, b of a rectangle with the same area. The green line shows the case n = 6. The apothem (sometimes abbreviated as apo [1]) of a regular polygon is a line

  9. Hexadecagon - Wikipedia

    en.wikipedia.org/wiki/Hexadecagon

    A regular hexadecagon is a hexadecagon in which all angles are equal and all sides are congruent. Its Schläfli symbol is {16} and can be constructed as a truncated octagon, t{8}, and a twice-truncated square tt{4}. A truncated hexadecagon, t{16}, is a triacontadigon, {32}.
