247
Verse 24. (Kujyā × Bhuja) / Karṇa = second segment of
Agrajyā (Krāntijyā × Koṭi) / Karṇa = first segment of Agrajyā
and Agrā = Sum of the two segments.
Comm. The first statement is based on the similarity
between the seventh triangle and others and the second on
the similarity between the 6th and the others.
Verse 25. (First segment of Agra × Bhuja) / Koṭi
= Un-mandala-Śaṅku and (Krāntijyā × Bhuja) / Karṇa
= Un-mandala-Śaṅku. (19)
Comm. Both the statements are based upon the
similarity of the sixth triangle and others. Thus un-
mandala śaṅku = U.S. = (H sin δ × H sin φ) / R =
= R sin δ sin φ.
Verse 26. (First segment of Agrā × Koṭi) / Bhūja
= Un-mandala-Śaṅku = Kujyā × Koṭi / Karṇa.
Comm. The first statement is based on the similarity
of the sixth latitudinal triangle and others and second
that between the seventh and others.
Sama-śaṅku − unmandala śaṅku = upper segment of
Sama-śaṅku.
Verse 27. (Agrā × Bhuja) / Karṇa = Kujyā
Taddhṛti − Kujyā = upper segment of Taddhṛti.
