Click bottom left corner to change modes Drag points on 1st mode Ellipsy warning maybe if you drag the points too fast There’s a circle for every set of 3 non colinear points. It takes the perpendicular bisectors of 2 lines made between the 3 points, and where the bisectors cross gives you the center, then you use distance formula to one of the points and set that to your radius
Given y=mx+b and y=nx+c, They cross at ((b-c)/(n-m), y((b-c)/(n-m))+b)
