( ̅̅̅̅ = 8公分,則直角∆ABC的面積為何? ) 如圖(五),直角∆ABC中,∠B = 90° ,∠A = 30° 。若AC

已知圓O的直徑為16公分,而圓心O到四條直線L、M、N、H的距離分別為16公分、10公分、 8公分、6公分,請問哪一條直線是割線?

如圖(四),A、B、C、D在圓上,且 ⃡AB 與 ⃡CD 交於P點,AD ⃡ 與 ⃡BC 交於Q點。若∠P = 45° 、∠Q = 35° ,則∠B是多少度?

( ⃡ 切圓O於C點,CD ) 如圖(三),CD ̅̅̅̅ = 8,OD ̅̅̅̅̅ = 10,則圓O的半徑長為多少?

已知圓O直徑是 16 公分,圓上A、B兩點將圓分成優、劣兩弧,若兩弧的度數比為5: 3,則圓心角 ∠AOB所對的劣弧長度為多少?

圓的直徑為 10 公分,設P點與圓心的距離為r公分,且P在圓周上,則下列敘述何者正確?

( ̅̅̅̅ = 15,若∠A = 90° ,則下列何者的值為 ̅̅̅̅ = 20、AC ) 如圖(一),直角∆ABC中,已知AB ? 5
