Change angle reference axis of canvas

[JatinBhuva]

See in normal canvas(default) angle if we have 0 deg angle then the line rests on the x-axis and the angle starts anti-clockwise.
But I want to start the angle from the y-axis and it should move the clockwise.

what I want to achieve Is below,
currently 0deg so the circle place is as given below image(blue ball) and as soon I increase the angle it moves anticlockwise
but what I want is if the angle is 0 then it(blue ball) should be at the top centre at red ring position. and if the angle increases it should move from there clockwise.

I'm giving coordinates to circle(blue) as below

  const newCoords = polar2Canvas(
        {
          theta:0,
          radius: r,
        },
        {
          x: center,
          y: center,
        }
      );

I'm not sure if this helps but I have a tutorial on trigonometry: https://www.youtube.com/watch?v=-lF7sSTelOg
