U mean numbers have shapes???????


Number Shapes. The square numbers are the numbers 1, 4, 9, 16, . . . that can be arranged in the shape of a square. The triangular numbers are the numbers 1, 3, 6, 10, . . . that can be arranged in the shape of a triangle. The first few triangular and square numbers are illustrated in Figure 1.
