ఇచ్చిన:

PQRS అనేది చక్రీయ సమలంబ చతుర్భుజం, PQ RSకి సమాంతరంగా ఉంటుంది.

PQ అనేది వ్యాసం & ∠QPR = 40°

భావన:

అర్ధ వృత్తంలో చేసిన కోణం లంబ కోణం.

చక్రీయ సమలంబ చతుర్భుజం యొక్క ఎదురెదురు కోణాల మొత్తం 180°.

లెక్కింపు:

త్రిభుజం PQRలో,

∠RPQ + ∠RQP + ∠QRP = 180° [త్రిభుజం యొక్క కోణాల మొత్తం]

⇒ 40° + ∠RQP + 90° = 180°

⇒ ∠RQP = 180° - 130° = 50°

∠RQP + ∠PSR = 180° [సంపూరక కోణాలు]

∴ ∠PSR = 180° - 50° = 130°
