Shape as Plane:

A 2-dimensional surface is called plane. A planar shape is bound by conceptual lines which constitute the edges of the shape. The characteristics of these conceptual lines and their inter-relationship determine the shape of the surface. These planar shapes have variety which may be classified as follows:

Geometric Shapes:

Shapes which are constructed mathematically are ‘geometric'. For example, square, triangle, circle and rhombus are geometric shape. See the Figure below (Fig.9).

Organic Shapes:

Shapes which are bounded by free flow curves usually represent dynamism and growth. They are often found in nature and are known as organic form. Fig.10
