The Shulbasutras of Baudhayana, Apastamba, Katyayana and Manava: With Text, English Translation and Commentary c7.414

c7.414

**12.8** This (rhombus) looks like two inverted (fore parts) of a cart (joined together). As in the case (of the isosceles triangle), a rectangle (twice the area of 7½ sq. *puruṣa*) is constructed and the mid-points of the eastern and western sides are joined to the mid-points of the southern and northern sides (of the rectangle, and the area lying outside these lines is cut off); this is the exact rhombus. (Bricks for this fire-altars are to be made in the same manner) as described in the case of the isosceles fire-altars.
