c8.t30.7

**4.6.** *Transformation of a rhombus into a square.* For transforming a rhombus *ENFS* into a square, *EF* and *NS*, the east-west and north-south lines are joined (Fig. 5). The isosceles triangle *NFS* is clearly sub-divided into two triangles *NOF* and *SOF*. These are now transferred and after invertion placed in their positions as *AEN* and *BES*. Thus the rhombus *ENFS* is transformed into the rectangle *ANSB*. This rectangle is transformed into a square by the *sūtra Kśl.* 3.2.
