And because you probably grew up in three-dimensional spaces full of right angles, your brain, in an attempt to make sense of these cues, can get fooled by a two-dimensional illustration. But what about people who don't see it?

而且因为你可能在充满直角的三维空间中长大，你的大脑在试图理解这些线索时，可能会被二维插图所欺骗。但那些看不到它的人怎么办？

" Departing to some distance, at right angles to the bee-line just ascertained, he liberates another, observes its course, and thus determines the position of the hive, which lies in the angle made by the intersection of the bee-lines."

“在与刚确定的蜜蜂航线成直角的地方远离一段距离，他释放另一只，观察其航向，从而确定蜂巢的位置，该位置位于蜜蜂航线交叉所形成的角度。”

Thanks to a phenomenon known as the Magnus effect (which also helps spinning balls curve), this pressure differential creates a force at right angles to the wind direction.

由于马格努斯效应（这也有助于旋转球弯曲），这差会产生与风向成直角的。

Depending on whether those axes are at right angles to each other and whether or not they're the same length or not, crystals will have different shapes and properties.

晶体所具有的不同形状和性质，取决于这些晶轴是否相互垂直以及它们的长度是否相同。

All right, come here. Now you have to remember, in pool, it's all about—take this stick— remember, it's all about the angles, the right angle, of course.

好的，过来吧。现在你得记住，在球台前，一切都取决于—拿着杆，记住，一切都取决于角度。确的角度，当然。

When I was at the museum, I took several hundred photographs and some of them were trying to find the right angle to illustrate the stegosaurus.

我在博物馆拍了百张照片，其中一些照片是尝试能够找到合适的角度来展示剑龙。

And just as the buildings nestle into and hug their surroundings, with few right angles, so the roofs arch and swoop and fall, mimicking the region's mountains.

因为建筑物嵌进了周围的环境，与周围的环境浑然一体，所以屋顶呈弧形猛扑而下，模拟这个地区的山脉。

It only lasts for a few minutes at sunset when the winter light hits the park's towering Horsetail Falls. At just the right angle.

日落时分，奇观只会持续数分钟的时间，发生的条件是冬日的阳光与公园的高耸的马尾瀑布以确的角度交汇。

But what if we point the cones so that the mirror is now at a right angle to the plane of symmetry?

但是如果我们把锥体指向镜面，使镜面与对称面成直角呢？

The awning had to be built at just the right angle, and all the pads had to be obscured.

遮阳篷的角度要合适，所有的护具都要遮住。

He understood right angles and clear instruction manuals. Assembly models and drawings. Things one could draw on paper.

他理解直角和清晰的产品说明，可以画到纸的东西。

The left should form at a right angle and the right knee should almost touch the floor.

左膝应呈直角，右膝应几乎触地。

As the herd approaches us, it swings round its front, at right angles, and makes off westward.

牛群接近时，会在突然跑开，找到合适得角度就向西奔逃。

The two lines on the left intersect each other at a right angle which is 90 degrees.

左边的两条线以90度的直角相交。

So, when the area is struck at the right angle with enough force, something interesting happens.

所以，当角度恰当、量充足的撞击该区域时，有趣的事情就会发生。
