Question

Match List I (Geometric Descriptions) with List II (Sanskrit Technical Names): 

List I		List II
A.	Rekhatraya-vritam kshetram	I.	Bahubhuja-kshetram
B.	Rekhachatushtaya-vritam kshetram	II.	Trijya
C.	Panchadi-rekhavritam kshetram	III.	Chaturbhujam
D.	Vyasardham	IV.	Tribhujam

• A. A-III, B-IV, C-II, D-I
• B. A-IV, B-III, C-I, D-II
• C. A-I, B-II, C-III, D-IV
• D. A-II, B-I, C-IV, D-III

Hint:

'Traya' = 3, 'Chatur' = 4, 'Bahu' = Many. Simply match the Sanskrit prefix with the number in the description.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
Geometry in the Siddhantas and the Lilavati is classified based on the number of boundaries (Rekhas/Bhujas).

Step 2: Detailed Matching of Geometric Terms:
1. Rekhatraya-vritam (A): A field enclosed by three lines. This is the definition of a Triangle (Tribhujam). (A matches IV).
2. Rekhachatushtaya-vritam (B): A field enclosed by four lines. This is a Quadrilateral (Chaturbhujam). (B matches III).
3. Panchadi-rekhavritam (C): A field enclosed by five or more lines. This is a general Polygon (Bahubhuja-kshetram). (C matches I).
4. Vyasardham (D): The half-diameter. In a celestial circle, this radius is the Trijya. (D matches II).

Step 3: Verification:
Sequence: A-IV, B-III, C-I, D-II. This corresponds to Option (2).

Step 4: Final Answer:
The definitions provide the elementary building blocks of Vedic geometry.
