Mapel : Matematika SMPMateri : Sudut - Lingkaran
∠QPO = 60°
Karena PQ = PR, maka membentuk segitiga sama kaki PQR dan garis OP tegak lurus garis QR.
∠QPR = 2 × ∠QPO
∠QPR = 2 × 60°
∠QPR = 120°
Karena Segitiga Sama Kaki, maka :
a. ∠PRQ
∠PRQ = ∠PQR
∠PRQ = (180° - 120°) ÷ 2
∠PRQ = 60° ÷ 2
∠PRQ = 30°
b. ∠QPO = 60° → Sudah diketahui di soal
c. Berdasarkan penjelasan di atas, maka :
∠RPO = ∠QPR ÷ 2
= 120° ÷ 2
= 60°
