Right Triangle Relationships
直角三角形关系
 |
The hypotenuse of a right triangle is related to the sides by the Pythagorean relationship: 直角三角形的斜边与其边之间存在勾股关系：
 From the two sides, either of the two acute angles may be found: 从两边可以找到任一锐角：
 |
Given any two sides, the angles may be found using the triangle trigonometric relationships. If the hypotenuse and one side are known, the other side may be calculated from:
给定任意两边，可以通过三角形三角函数关系求出角度。如果已知斜边和一个边，另一个边可以由以下公式计算：
