Startangle and sweepangle

[Sunil Batra]

I was just wondering what is a start angle and sweepangle in a
graphic.drawarc(pen,rectangle,startangle,sweepangl e)

I have got the coordinates of the rectangle but i want to get the start
angle and sweep .

I am drawing an arc using 3 points .

How do i calculate the startangle and sweepangle

Consider a clock-face.

StartAngle 0 is at 3:00

SweepAngle is how many degrees you go around the clock in a clockwise
direction

0,90 draws a quarter circle in the lower-right quadrant between 3:00 and
6:00, 180,180 draws a half circle over the top between 9:00 and 3:00
