When we talk about free form shapes, it can be curve, lines or simple concave or convex polygons.
1. The shape can be closed or open.
2. The curve can cross each other, that is lines or doodled lines may intersect.
3. The free form shape consist of either lines or doodled lines, which we call an open curve.
When we talk about Geometric Shapes, it consist only of Polygons, which consist of triangles, Quadrilaterals, polygons.
1. The curve is simple closed curve.
2. It consist entirely of line segments.
3. The intersection within the curve is a point.
