context.arcTo( x1, y1, x2, y2, r );
Parameters:
- x1: This parameter specifies the x-coordinate of the first tangent.
- y1: This parameter specifies the y-coordinate of the first tangent.
- x2: This parameter specifies the x-coordinate of the second tangent.
- y2: This parameter specifies the y-coordinate of the second tangent.
- r: This parameter specifies the radius of the arc.
