दिइएको चित्रमा O वृत्तको केन्द्रविन्दु र PQRS एउटा चाक्रिय चतुर्भुज हो ।
In the given diagram, O is the centre of the circle and PQRS is a cyclic quadrilateral.
[Figure: Circle with centre O and cyclic quadrilateral PQRS inscribed, with P, Q, R, S on the circle]
(a) \(\angle QRS\) र वृहत \(\angle QOS\) बिचको सम्बन्ध लेख्नुहोस् ।
Write the relationship between \(\angle QRS\) and reflex \(\angle QOS\).
(b) यदि \(\angle QPS = 46^\circ\) भए \(\angle QOS\) को मान पत्ता लगाउनुहोस् ।
If \(\angle QPS = 46^\circ\), find the value of \(\angle QOS\).
(c) \(\angle QPS + \angle QRS = 180^\circ\) हुन्छ भनी प्रयोगद्वारा प्रमाणित गर्नुहोस् ।
(3 से.मि. भन्दा बढी अर्धव्यास भएका दुईवटा वृत्तहरू आवश्यक छन् ।)
Verify experimentally that: \(\angle QPS + \angle QRS = 180^\circ\).
(Two circles having radii more than 3 cm are necessary.)
