to obtain the value of *tṛtīyākaraṇī* by both Āpastamba (*Āśl.* 2.2 and 2.3) and Kātyāyana (*Kśl.* 2.10 and 2.11).

According to them, a square on the producer *AB* (=√3a) when divided into nine equal parts by means of three parallel lines drawing from both sides, produces the square, *EBGF* which is one-ninth of the square *ABCD* (Fig. 6). Then EB²=1/9 AB² or EB =⅓ AB =⅓ √3 a. =1/(√3) a.
