互补角(complementary angles)的定义是两个角的度数之和为90°。以下是对每个选项的逐一分析:- **选项A**:角度和为180°。这是补角(supplementary angles)的定义,而非互补角,因此错误。- **选项B**:角度和为90°。此描述完全符合互补角的定义,正确。- **选项C**:角度相等。这描述的是全等角或对等角,与互...

In geometry, complementary angles are defined as two angles whose sum is 90 degrees. Two complementary angles when put together form a right angle. Learn the differences between complementary and supplementary angles.
Two angles are Complementary when they add up to 90 degrees (a Right Angle). They don't have to be next to each other, just so long as the total is 90 degrees. Examples: • 40° and 50° are complementary angles. • 60° and 30° are complementary angles. • 5° and 85...
