直角

If the mansion stood on a hypersphere slightly greater in diameter than the mansion grounds, a person could move from any point to any other with what, in three-space, would seem to be right angles.

如果这座大厦建造在一个比地基更多维的超球面上，一个人就可以从任意在三维空间内看上去是直角的地方从一点移动到另一点。

Ratio of the hypotenuse to the opposite side .

直角三角形的斜边与一个角的对边之比。

Either side of a right triangle that is not the hypotenuse.

直角三角形的一个角的邻边与斜边之比。

Also remember that Phi is calculated from the hypotenuse of a 1 by 2 rectangle.

同样要知道黄金率是从一个被一分为二的矩形中的对角线也就是直角三角形的斜边中计算来的。

Hypotenuse of the composite triangle is actually not a straight line – it is made of two lines.

直角三角形的斜边不是直线-是两条线组成的。

The sine of an angle is the ratio of the length of the opposite side to the length of the hypotenuse.

正弦是股与弦的比例，余弦是余下的那条直角边与弦的比例。

Hint: think of y as the altitude of a triangle with hypotenuse as base.

并提示说：把y 看做是以直角三角形斜边上的高。

One of the small sides of a right-angled triangle is 5cm and the perpendicular height drawn against the hypotenuse is 3cm.

一直角三角形的小边中的一5 厘米和垂直高度反对斜边是3 厘米拉。
