SHAPE AND SPACE

            For many years, people told stories by drawing and painting pictures. Shape and space is the basic of geometry. Architects in ancient Greece were the people who directed the building work. They have to make buildings pleasing to the eye. Shape and space play a very important role in their work. Shapes with no thickness, which have just length and width are known as two-dimensional shapes. Example of two-dimensional shapes are squares, rectangles, triangles, etc.

            The most common objects that we see and handle everyday are those with three dimensional which are called solid shapes. The objects around us are examples of solids. Solids take up space. Solids may be skeletons of shapes made with wires, straws or sticks. Example of three-dimensional shapes are cubes, cuboids, etc.
