    e.Graphics.DrawRectangle(Pens.Black, rectangle1)
    e.Graphics.DrawRectangle(Pens.Red, rectangle2)

    If (rectangle1.IntersectsWith(rectangle2)) Then
        rectangle1.Intersect(rectangle2)
        If Not (rectangle1.IsEmpty) Then
            e.Graphics.FillRectangle(Brushes.Green, rectangle1)
