   圓的基本性質(Basic Properties of Circles) 10.0. 在幾何中有關圓形的常見詞彙(Common Terms in Geometry about Circles) 喺講同圓形有關嘅幾何定理嘅時候,我哋會見到一D喺初中時比較少見嘅詞語。 為方便大家日後嘅學習,喺度先講解吓依D詞語: 弧線 (arc) :圓形周界嘅一部份。 假如頭尾兩點分別係點A、B ,弧AB可記作 。 弦線 (chord) :將弧線頭尾兩點相連嘅直線,可記作AB。 AB. 弓形 (segment):一條弧線同佢相應嘅弦線所包圍嘅部份。 圓心角 (angle at centre):從弧線兩端劃出兩條直線到圓心所形成嘅角 (因隻角係喺圓心,所以叫圓心角)。
