Curve
Curve is a combination of a lot of small segmented straight line. So small segment of straight line is the source of all kind of curves not in the drawing board but also in our nature and life. Curve has some strange things over straight line. You can create a curve with some small segmented straight line but the reverse is not possible. If you join few curves it will create a complex curve but not a cruve. But putting curves of same shape and curvature may create a straight line like thing (not really a straight line).
