I was trying to solve a problem which involved covering a given arc by minimal side of a square. I came to the conclusion that I had to write the equation of the arc, however it posed a great deal of difficulty to me. Kindly help. Thank you

Lets say the points have coordinates (x1,y1),(x2,y2),(x3,y3).
Assume, center of circle has coordinates (x0,y0) and radius r. Now, as the points are on circle,
(x0-x1)^2 + (y0-y1)^2 = r^2
(x0-x2)^2 + (y0-y2)^2 = r^2
(x0-x3)^2 + (y0-y3)^2 = r^2 Now try to do something with these equations.
