What are the starting and ending angles of arcs in HTML5 canvas?

The arc() function has the following definition that shows the usage of start and ends angle −

arc(x, y, radius, startAngle, endAngle, anticlockwise)

The method has the following parameters:

• x and y are the center coordinates of the circle.
• Radius is the radius of the circle.
• StartAngle and EndAngle define the starting and ending points of the arc in radians. The starting and ending angles are calculated from the horizontal axis (i.e. the x-axis).
• Anticlockwise is a Boolean value. When true, an arc is drawn in the counterclockwise direction, otherwise it is clockwise.
