Question

चित्र में वृत्त की त्रिज्या OA=√2 सेमी तथा जीवा AB = √2 सेमी APB का मान ज्ञात कीजिए।

Answer 1

∠APB = 30°   यदि  वृत्त की त्रिज्या OA=√2 सेमी तथा जीवा AB = √2 सेमी

Step-by-step explanation:

वृत्त की त्रिज्या OA=√2 सेमी

जीवा AB = √2 सेमी

OB = वृत्त की त्रिज्या

=> OB = OA

=> OB = √2 सेमी

OA = OB = AB =  √2 सेमी

=> ΔAOB  समबाहु त्रिभुज

=> ∠AOB = 60°

∠AOB = 2∠APB

=> 60° = 2∠APB

=> ∠APB = 30°
