In the limit, a sequence of regular polygons with an increasing number of sides approximates a circle, if the perimeter or area is fixed, or a regular apeirogon (effectively a straight line), if the edge length is fixed. The words for polygons Math. Gauss, C. F. §365 and 366 in Disquisitiones Arithmeticae. In geometry, a polygon is a plane figure that is described by a finite number of straight line segments connected to form a closed polygonal chain or polygonal circuit. New York: Graylock Press, 1965. The interesting aspect is that the name of a polygon highlights the number of sides it possesses. Boca Raton, FL: CRC Press, 1995. A regular polygon is an -sided polygon : An Elementary Approach to Ideas and Methods, 2nd ed. For example, a triangle has three sides, and a quadrilateral has four sides. Polygons come in all different shapes and sizes. are "constructible" using the A polygon has 54 diagonals. Regular polygons have sides and angles that are all the same. Harris, J. W. and Stocker, H. "Regular -gons (Polygons)." Regular Polygon If all the sides and interior angles of the polygon are equal, then it is known as a regular polygon. having all sides the same length and all interior angles the same).
