The arc() method is used to create an arc/curve i.e. circles, or parts of circles.
Syntax:
context.arc(x, y, r, sAngle, eAngle, counterclockwise);
Parameters:
- x: This parameter specifies the x-coordinate of the center of the circle.
- y: This parameter specifies the y-coordinate of the center of the circle.
- r: This parameter specifies the radius of the circle.
- sAngle: This parameter specifies the starting angle, in radians( 3 o’clock position of the arc’s circle denotes 0).
- eAngle: This parameter specifies the ending angle in radians.
- counterclockwise: This parameter specifies the drawing should be clockwise or anticlockwise. It is false by default which denotes clockwise.
