You know, cosine is adjacent over hypotenuse.

你们知道 cos是邻边除以斜边。

So you have the opposite over the hypotenuse.

里是对边比斜边。

I get it! Sin is opposite hypotenuse... Yes.

我懂了，弦是对边比斜边。是。

So this is equal to cosine of the angle.

cosθ邻边/斜边。

Opposite over hypotenuse is equal to sine of an angle.

斜边分之对边 值即是 sin 函数值。

And so this is going to be equal to what?

相对个角 里是邻边/斜边？

Arrange them so that their hypotenuses form a tilted square.

将它们排列起来，使其斜边形成一个倾斜形。

Take four identical right triangles with side lengths a and b and hypotenuse length c.

取四个全直角三角形，两边分别长 a 和 b，斜边长 c。

Root 2 simply is the hypotenuse of a right triangle

而 √2 只是两边长度为 1 直角三角形之斜边。

The most famous relation in geometry is the relation between the sides and the hypotenuse of a right triangle.

几何中最著名关系是直角三角形边和斜边之间关系。

What involves the hypotenuse and the opposite side?

什么涉及斜边和对边？

You know, I was blown away that the square of the hypotenuse was the sum of the squares of the opposite sides.

斜边平直角边平和可把我给惊呆了。

So what involves the opposite and the hypotenuse?

那么什么涉及对立面和斜边呢？

After the hymn, the teacher taught students the hypotenuse.

赞美诗后，老师教学生直角三角形斜边。

They looked like real stones because of the way they were cut-flat with beveled edges.

它们看起来像真石头， 因为它们被切割成带有斜边平整式。

It's adjacent over hypotenuse. And that's square root of 3 over 2.

它在斜边上相邻。那是 3 除 2 平根。

When you draw a vector, it's a lot like the HYPOTENUSE of a right angle triangle.

That states that the squares of the sides of a right triangle add up to the square of its hypotenuse.

表明直角三角形各边平加起来其斜边平。

He loved nothing better than a vertical path; but this way seemed indefinitely prolonged, and instead of sliding along the hypothenuse as we were now doing, he would willingly have dropped down the terrestrial radius.

他最喜欢垂直小路。但条路似乎无限期地延长，他不会像我们现在那样沿着斜边滑动，而是心甘情愿地沿着地球半径下降。
