यवस्य तु तुरीयांशं पूर्वापराह्नयोर्गता।
बिन्दुद्वयान्तरं भ्रान्तश्शंबरानन पुच्छकम्।। ३१
दक्षिणोत्तरमित्युक्तं अन्यथा वा ऽपि कथ्यते।

Having a radius equal to the three fourth of the east-west line, he should
draw a segment of a circle, keeping the east bindu as the centre and another
segment keeping the west bindu as the centre. The point where the two
segments cut each other on the south of the east-west line and the point where
the two segments cut each other on the north of the same line are to be joined.
The inner space in which the two segments cut each other will look like the
face and tail of a fish. The line which joins the south point and the north point
is known as the south-west line. Marking of the east-west line and north-south
line is told in another way also.
