సూత్రం:
అర్ధ వృత్తంలో చేసిన కోణం లంబ కోణం.
వృత్తం యొక్క అదే విభాగంలో ఏర్పడిన కోణాలు కొలతలో సమానంగా ఉంటాయి.
లెక్కింపు:
B మరియు R లను కలపడం ద్వారా BR ఏర్పడుతుంది.
∠ARS + ∠ARP = 180° [సమాంతర జత]
⇒ ∠ARP = 180° - 125° = 55°
∠ARB = 90° [అర్థ వృత్తంలో చేసిన కోణం]
⇒ ∠ARP + ∠BRP = 90°
⇒ ∠BRP = 90° - 55° = 35°
∠BRP = ∠PAB = 35° [ఒకే విభాగంలో చేసిన కోణాలు]
∴ ∠PAB = 35°
