    Resolved [RESOLVED] Check whether point is in a circle

    Hi all again.

    Can anyone explain how to check whether or not a point lies whithin a circle.
    point = x1,y1
    circle = (x2-a)²+(y2-b)²=r²

    Argh, sorry, done it again.
    Need to find out how to delete threads.

    Obviously need to check that the hypotenuse of the point is less than the radius of the circle.
