# HTML | canvas arcTo() Method

The canvas arcTo() Method is used to create an arc/curve between two tangents on the canvas.This method defines an arc in the extension of a straight line or another figure. This method is generally used to create rounded corners.

Syntax:

`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.
