triangle: One of the three angles is a right Angle. The other two are acute angles.───直角三角形：有一个角是直角，有两个角是锐角。
For less acute angles, on the other hand, gravel traps and tyre stacks are absolutely indispensable.───对不太锐利的弯角来说，另一边的沙砾缓冲区和轮胎墙是绝对必不可少的。
If you test by the triangle's angles, possible types are right, acute, obtuse, or equiangular.───如果您用三角形的角度进行测试，那么可能的类型是直角、锐角、钝角或等角三角形。
