अवधारणा:
अर्धवृत्त में बना कोण समकोण होता है।
एक वृत्त के एक ही खण्ड में बनने वाले कोणों की माप बराबर होगी।
गणना:
B और R को मिलाने पर BR बनती है।
∠ARS + ∠ARP = 180° [रेखीय युग्म]
⇒ ∠ARP = 180° - 125° = 55°
∠ARB = 90° [अर्धवृत्त में बना कोण]
⇒ ∠ARP + ∠BRP = 90°
⇒ ∠BRP = 90° - 55° = 35°
∠BRP = ∠PAB = 35° [एक ही खंड में बने कोण]
∴ ∠PAB = 35°
