Find the points of the circle?

Question

PHP

I draw an image.
There is a 500 x 500 pixel square. A circle with a center of 255 x 225 is inscribed in it.



You need to divide the square into n equal parts (I have 27).
How to find these points of the circle to draw lines for dividing?

Answer 1

School trigonometry course:
Entire circle - 2*PI radians. One sector that you need - k = 2*PI / 27
Further in the loop k * i (loop counter) - translate into coordinates with zero in the center of the circle (Yes, you will need to use sines / cosines here)
Then translate these coordinates into screen . Everything. I think you'll figure it out yourself.

Answer 2

look for points and draw imagearc
