sqrt(pow(abs(x - xc), 2) + pow(abs(y - yc), 2)); And the angle between this 2 points with atan2, like this: atan2(abs(y - yc), abs(x - xc)); Where xc, yc is the center point and x, y is the only vertex know. And with that data i do: void polygon(int xc, int yc, int radius, double angle, int sides) {. int i;
I have been trying to figure out how to write a simple program to compute the x,y points for creating a regular polygon of n sides. Can someone give me some code examples that don't use preexisting functions that draw polygons?
23 Ιαν 2018 · The header file graphics.h contains drawpoly () function which is used to draw polygons i.e. triangle, rectangle, pentagon, hexagon etc. Syntax : void drawpoly( int number, int *polypoints ); where, number indicates (n + 1) number of points. where n is the number of vertices in a. polygon. polypoints points to a sequence.

22 Απρ 2021 · Given an integer N representing N sided regular polygon, the task is to find the angle made by the sides on the centre of the polygon that is the central angle. The central angle is the angle formed by the two vertices forming an edge and the centre.
16 Απρ 2014 · The goal of this code golf is to draw a regular polygon (one with equal side lengths) given the number of sides and radius (distance from center to vertex). The number of sides and the radius can be entered via a file, STDIN, or just a plain old variable. Use whatever is shorter in your language.
You are given an angle $$$\text{ang}$$$. The Jury asks You to find such regular $$$n$$$-gon (regular polygon with $$$n$$$ vertices) that it has three vertices $$$a$$$, $$$b$$$ and $$$c$$$ (they can be non-consecutive) with $$$\angle{abc} = \text{ang}$$$ or report that there is no such $$$n$$$-gon.
