解题方法
10 . 高三新教学楼启用后,从一些教室窗口就能看到殷高路对面居民房平改坡后的屋顶(如图).其中
是屋脊线,
是屋檐线,
是屋顶坡面,
是一个与水平面垂直的带气窗的竖直面,
是气窗屋顶的屋脊线且
与竖直面
垂直.
![](https://img.xkw.com/dksih/QBM/editorImg/2023/12/16/3cacf3fc-d38d-4a25-9bc2-80a2a7d0347d.png?resizew=252)
小张和小王对屋顶进行研究,提出了下面一些假设:
①两条屋脊线
与
互相垂直且都与水平面平行;
②气窗屋顶的两个坡面
与
互相垂直且与水平面的所成角相等;
③屋顶坡面
与水平面所成角为
.
(1)小张认为还需假设屋脊线
与带气窗的竖直面
是平行关系.而小李认为前面的假设已经够了,不需要再提出这个假设.请你判断哪位同学正确?证明你的判断.
(2)根据小张和小王的假设,试求气窗屋顶的一个坡面
与屋顶坡面
构成的阴脊线
(是平面
与平面
的交线)与水平面所成角的大小.(用反三角函数表示)
