वर्गमूल सर्पिल में \(\sqrt{21}\) बनाने के लिए \(\sqrt{20}\) पर (1) इकाई लंब क्यों पर्याप्त है?
Why is a (1) unit perpendicular on \(\sqrt{20}\) sufficient to construct \(\sqrt{21}\) in a square root spiral?
Explanation opens after your attempt
A. (\(\sqrt{20}\)2+12=21)
Concept
Pythagoras theorem uses the sum of squares. Therefore \(\sqrt{20}\) and (1) form hypotenuse \(\sqrt{21}\).
Why this answer is correct
The correct answer is A. (\(\sqrt{20}\)2+12=21). Pythagoras theorem uses the sum of squares. Therefore \(\sqrt{20}\) and (1) form hypotenuse \(\sqrt{21}\).
Exam Tip
पाइथागोरस प्रमेय में वर्गों का योग लिया जाता है। इसलिए \(\sqrt{20}\) और (1) से कर्ण \(\sqrt{21}\) बनता है।
