"We need to tell it to call the Point class constructor, and pass these parameters"... Why?

I do not get why we must add :base(x,y) if we've already created the MapLocation constructor with two parameters of int x and y.

It's more confusing to me because the task that comes up after regarding the polygon and square bares little resemblance to the video in terms of the base constructor parameters.

Any help would be appreciated!

 class MapLocation : Point 
    {
        public MapLocation(int x, int y) : base(x, y) //I don't get this bit!!!
        {

        }
    }

:point_right: If you don't specify an alternative base constructor, it will use the default.

In this case, the base constructor that takes two parameters is desired intead of using the default (which would take no parameters).
