    Circle Within a Canvas with multiple segments cone shaped. Find I am in which segment

    I have a circle drawn within a canvas HTML5. I have multiple segments in the circle. I have start and end angle of each segment also I have got the radius.
    I know that we can get angle using the mouse coordinates and then depending on which angle range it falls in we would know that the point lies in which segment. I have only got this as theory but do not know how to do it.

    Please help.

    This is a repost of another thread Find point if within circle and within a sector Why????

    There are a number of solution on your old post, I just expanded on mine there. This post is not needed.
