<div class="markdown level1 summary"><p>Draws a line segment and an arc.
The line segment is drawn from the position which is defined by <code>radius</code> and <code>startAngle</code>.
The arc is drawn along the perimeter of a circle with the given radius and center.
The length of the arc is defined by the given start and sweep angles.</p>

<div class="markdown level1 remarks"><p>The arc is drawn by constructing an imaginary circle around the specified center point with the specified radius.
The starting point of the arc is determined by measuring counterclockwise from the x-axis of the circle
by the number of degrees in the start angle. The ending point is similarly located by measuring counterclockwise
from the starting point by the number of degrees in the sweep angle.
If the sweep angle is greater than 360 degrees,the arc is swept multiple times.</p>

defines the curve of the arc. The arc extends in the current drawing direction from the point where it intersects
