垂直角, 对顶角
one of a pair of opposite angles made by two intersecting lines, which are always equal
- Vertical angles are always congruent to each other.
垂直角总是彼此全等。
- The theorem stating that vertical angles are equal is a fundamental concept in geometry.
垂直角相等的定理是几何学中的一个基本概念。
- In the diagram, angle A and angle B are vertical angles and thus have the same measure.
在图中，角A和角B是对顶角，因此具有相同的度数。
- When proving the equality of vertical angles, you can use the properties of intersecting lines.
证明垂直角相等时，可以使用相交线的性质。
- If one vertical angle is 45 degrees, the opposite vertical angle must also be 45 degrees.
如果一个垂直角是45度，那么相对的垂直角也必须是45度。
