## Example
Create a circle:
Your browser does not support the Canvas tag.
JavaScript:
var c=document.getElementById("myCanvas"); var ctx=c.getContext("2d"); ctx.beginPath(); ctx.arc(100,75,50,0,2*Math.PI); ctx.stroke();

**Note:** Internet Explorer 8 and earlier versions do not support the element.

## Definition and Usage
The arc() method creates an arc/curve (used to create circles or parts of circles).
**Tip:** To create a circle with arc(), set the start angle to 0 and the end angle to 2*Math.PI.
**Tip:** Use the [stroke()](#) or [fill()](#) methods to actually draw the arc on the canvas.
Center:
arc(**100,75**,50,0*Math.PI,1.5*Math.PI)
Start angle:
arc(100,75,50,**0**,1.5*Math.PI)
End angle:
arc(100,75,50,0*Math.PI,**1.5*Math.PI**)
| JavaScript syntax: | _context_.arc(_x,y,r,sAngle,eAngle,counterclockwise_); |

## Parameter Values
| Parameter | Description |
| --- | --- |
| _x_ | The x-coordinate of the center of the circle. |
| _y_ | The y-coordinate of the center of the circle. |
| _r_ | The radius of the circle. |
| _sAngle_ | The starting angle, in radians (the 3 o'clock position on the circle is 0 radians). |
| _eAngle_ | The ending angle, in radians. |
| _counterclockwise_ | Optional. Specifies whether the drawing should be counter-clockwise or clockwise. False = clockwise, true = counter-clockwise. |
