对的 是15度角

No random lines here. You should fold 15 degree lines and make 3 grids
这里没有随机的线。你要折一些15度角的线还有做三等分

You can use that way to fold 30 degree lines and then fold 15 degree.
你可以这样折出30度角的线，然后再平分做15的


So you can fold those lines by fold 15 degree lines and make 3 grids.
只看15度角跟三等分的话大概能找到这些线。


and then
然后




finally，I don't certain this
这个我不太确定

Thank you Master  .The reward for your help I will mark as solved
The reason I thought the line random because at first glance (green) the angle seems to be equal.I thought was  45° then 22.5 .Where they meet the diagonal plane although angles equal where they fall does not apportion equally
伟大的老师，Yongije有没有在绿色和黄色区域内找到的方法？
