Draw Pies and Arcs

Pie() and Arc() draw wedges and arc segments. The first four arguments are x1, y1, x2, and y2, the coordinates of the rectangle to inscribe. The last two arguments are the starting and ending angle in degrees, where 0 degrees is 12 o'clock and the arc or slice is drawn clockwise from start to finish.
