Wyoming is also a square because it has that nickname(see State nicknames). If a circle is circumscribed around a square, the area of the circle is (about 1.57) times the area of the square. If a circle is inscribed in the square, the area of the circle is (about 0.79) times the area of the square. A square has a larger area than any other quadrilateral with the same perimeter (). A square tiling is one of three regular tilings of the plane (the others are the equilateral triangle and the regular hexagon). The square is in two families of polytopes in two dimensions: hypercube and the cross polytope. The Schläfli symbol for the square is {4}. The square is a highly symmetric object. There are four lines of reflectional symmetry and it has rotational symmetry through 90°, 180° and 270°. Its symmetry group is the dihedral group . गैर यूक्लिड ज्यामिती In non-euclidean geometry, squares are more generally polygons with 4 equal sides and equal angles. In spherical geometry, a square is a polygon whose edges are great circle arcs of equal distance, which meet at equal angles. Unlike the square of plane geometry, the angles of such a square are larger than a right angle. In hyperbolic geometry, squares with right angles do not exist. Rather, squares in hyperbolic geometry have angles of less than right angles. Larger squares have smaller angles. Examples: 200pxSix squares can tile the sphere with 3 squares around each vertex and 120 degree internal angles. This is called a spherical cube. The Schläfli symbol is {4,3}.200pxSquares can tile the Euclidean plane with 4 around each vertex, with each square having an internal angle of 90 degrees. The Schläfli symbol is {4,4}.200pxSquares can tile the hyperbolic plane with 5 around each vertex, with each square having 72 degree internal angles. The Schläfli symbol is {4,5}. देखें घन पायथागोरस सिद्धांत बाहरी कडि़याँ वर्ग आंकलन Animated course (Construction, Circumference, Area) Square Square Definition and properties of a square With interactive applet Animated applet illustrating the area of a square श्रेणी:ज्यामिति श्रेणी:प्राथमिक आकार
