“Height”的概念、定义、习题解题方法及翻译-数学辞典

单词	Height
释义	height Let $A B C$ be a given triangle. A height of $A B C$ is a line segment drawn from a vertex to the opposite side (or its prolongations) and perpendicular to it. So we have three heights in any triangle. The three heights are always concurrent and the common point is called the orthocenter. In Euclidean geometry thelength of the segment ”height” is sometimes referred to as the height. In the following figure, $A D, B E$ and $C F$ are heights of $A B C$ .
