?perpendicular一詞源于拉丁文的perpendiculum,意為“垂直的”,是一個常用的幾何學術語。它可以作為形容詞或名詞使用,表示兩條直線或面之間的垂直關系。在日常生活中,我們也可以用這個詞來形容某物或某人的姿勢或態(tài)度。
正確讀音為/prpndkjlr/,其中重音在第二個音節(jié)上。
perpendicular作為形容詞時,意為“垂直的”、“垂直于地平線的”。:The tower stands perpendicular to the ground.(這座塔垂直地矗立在地面上。)它也可以表示“陡峭的”、“筆直的”,如:The mountain has a perpendicular slope.(這座山有一條陡峭的山坡。)
作為名詞時,perpendicular指代一條垂直線或面,也可以指代一個與主要方向相交成90度角的方向。:The carpenter used a square to make sure the wall was at a perfect perpendicular.(木匠用方尺來確保墻壁處于完美的水平狀態(tài)。)
除了幾何學和日常生活中,perpendicular還可以用來形容某人或某物的姿勢或態(tài)度。比如說:Her arms were crossed and her body was perpendicular to the ground, showing her defiance.(她雙臂交叉,身體筆直地站立著,表現(xiàn)出她的挑釁。)
