Shalini and Rajani like drawing pictures. One day teacher asked the students to draw pictures of chairs in their homes. Rajni looked at one of Shalini's pictures and said, "This is not a chair". Shalini said, "It is a chair." The teacher said, "This is a chair. It is how the chair looks when you look at it from the top."

Think about: Have you looked at a chair from the top, from the side and from the front? Does the chair look the same or different when seen from different sides?
