is there a general formula to describe regular polygons

Question

is there a general equation that can describe a regular polygon (in the 2D Cartesian plane?), given the number of sides required?

The idea is that as the number of sides in a regular polygon goes to infinity, the regular polygon approaches a circle. Since a circle can be described by an equation, can a regular polygon be described by one too? For our purposes, this is a regular convex polygon (triangle, square, pentagon, hexagon and so on).

Answer 1

regular polygon: giv the length av 1 side & n=number sides, & kan kalkulate

evreethang NE-1 kood ever ask for

start: the senter angel=360 deg/n...thats the angel tween lines from senter

av polygon tu the points weer 2 sides meet

If yu projekt NE side forward, yu see angel tween the projekshun & next side

this angel is same as senter angel.. zampel: n=5 (pentagon) senter angel=72 deg

From this, yu kan get more than yu kood majin
