यदि \(OQ^2-OP^2=1\) और (PQ=1), तो (OP) और (PQ) के बीच कोण कैसा होगा?
If \(OQ^2-OP^2=1\) and (PQ=1), what type of angle is between (OP) and (PQ)?
Explanation opens after your attempt
B. समकोणRight angle
Concept
This relation matches Pythagoras theorem, so (OP) and (PQ) are perpendicular. This right-angle construction is essential in the square root spiral.
Why this answer is correct
The correct answer is B. समकोण / Right angle. This relation matches Pythagoras theorem, so (OP) and (PQ) are perpendicular. This right-angle construction is essential in the square root spiral.
Exam Tip
यह संबंध पाइथागोरस प्रमेय जैसा है, इसलिए (OP) और (PQ) लंब होंगे। वर्गमूल सर्पिल में यही समकोण रचना जरूरी है।
