                  tanGram

                  Tangram is a 1000 year old Chinese puzzle of shapes. There are two                          3       4

                  ways to make a shape with tangram. One way is to try to duplicate the                          5  6
                  shape from a simple outline shape and another way is to imagine and                         7        2

                  create new designs. There are different kinds of tangrams.                                      1
                  In the figure given alongside, it is made with 7 pieces formed by cutting a square. There

                  are five triangles (1, 2, 3, 4 and 5) and 2 quadrilaterals (6 and 7).

                  We make different figures by arranging these pieces of the tangram.
                  Observe the following figures.

                                                                                         Think and Answer
