互为余角和互为补角是几何中的两个重要概念．它们说明的都是两个角之间的数量关系．在学习这部分内容时，应注意以下三个方面：一、正确理解概念1．如果，则做互为余角，其中是2的余角，也是的余角．如果，则与叫做互为补角，其中是的补角，也是的补角．2．互为余角与余角，互 Complementary angles and complementary angles are two important concepts in geometry. They explain the relationship between the two corners. In learning this part of the content, you should pay attention to the following three aspects: First, the correct understanding of the concept 1. If you do, then do more than one corner, which is 2’s more than a corner, but also the remaining corner. If it is, then it is called a complementary angle, which is a supplementary angle, and also a supplementary angle. 2. Each other is Yujiao and Yujiao, each other
