HTML canvas arc() Method

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.

Example 1:

<!DOCTYPE html>
<html>

<head>
    <title>
        HTML canvas arc() Method
    </title>
</head>

<body style="text-align:left;">

    <h1>GeeksforGeeks</h1>

    <h2>HTML canvas arc() Method</h2>

    <canvas id="GFG" width="500" height="200">
    </canvas>

    <script>
        var doc_id = document.getElementById("GFG");
        var context = doc_id.getContext("2d");
        context.beginPath();
        context.strokeStyle = 'green';
        context.arc(100, 50, 40, 0, 2 * Math.PI);
        context.stroke();
    </script>
</body>
