So, this headline is looking at the same story, but from the opposite angle.

所以，这个标题是讲同样的报道，但从相反的角度。

For example, it is known that if we draw perpendiculars to the sides of a triangle from the opposite angles, all three perpendiculars meet in a point.

例如，众所周知，如果我们从相反的角度向三角形的边绘制垂线，则所有三个垂线都会交于一点。

Everybody looked up at the open windows in the houses at the opposite angles of the converging streets; but they were either blank, or filled by laughing listeners.

每个人都抬头看着交汇街道对角处房屋中敞开的窗户；但他们要么是空白，要么被笑着的听众填满。
