c8.t28.51

**1.3** This gives a general method of construction of a square or a rectangle. In a given cord marks are given for *śroṇi*, *aṃsa* and *nirañchana* points. Two knots are fixed at the two ends of the cord; then fixing the two ends of the cord to the poles at the two ends of the east-west line, the cord is drawn by the *nirañchana* mark on either side of the line. By interchanging the knots at the two ends, the operation is repeated. Further details as to the length of the cord corresponding to a given distance between the two poles (the length of the altar) and where the *nirañchana* mark is to be given are discussed in the subsequent rules.
