calculate centre of a circle
How can I calculate the centre of a circle if I have three points on the perimeter.
I could do it by drawing (find the verticals on the middle of each connecting line of the points, these verticals will cross in the centre of the circle), it'S called the "surrounding circle of a triangle". The calculation of that position is what I'm looking for.

Complex, I know, but this site has how to find the coordinates of the center (providing you know how to find matrix determinants):

check equations 11 and 12
if not, you can calculate two of the perpendicular bisectors of the sides, then find their intersection

I'm ashamed, but the same question has been asked before, and the given code works. Thanks anyway.
