 Tangram is a 1000 year old Chinese shape puzzle. There are two ways   3  6  4  (a)   (b)
 to make shapes with tangram. One way is to try to duplicate the shape   5  2  11  12  1

 from a simple outline shape and another way is to imagine and create   7  9 10  2 3
 new designs. There are different kinds of tangrams.   1  8  7  6  5  4   _____________   _____________

 In the figure given alongside, there are 7 pieces formed by cutting a square. There are   (c)   (d)
 five triangles (1, 2, 3, 4 and 5) and 2 quadrilaterals (6 and 7).                      _____________

 We can make different figures by arranging these pieces.   _____________
