Her design is made up of two long black granite pieces that meet at an angle.

But because there's this lone pair here, it's pushing down on the other bonds, 5° so we end up with an angle of less than 109 . 5 degrees.

但因为这里有孤对，它会把其它键向下压，所以键角会小于109。

You can imagine that if a vector is viewed from an angle, then its components will vary with the perspective.

你可以想象一下,如果换一个角度观察矢量,其分量会相应地发生变化

Another way to represent a point in a plane is I've got a radius and I've got an angle from the x-axis, right, and that's a standard thing you might do.

平面上面的点的方法,也就是极坐标,上面那种方法其实是，如果你们喜欢我这么说的话,笛卡尔坐标表示法。

And they recognized right away she is an angle.

他们会马上意识到她是天使。

So if we still have an angle of a 109 . 5 degrees, and again, we still have four unpaired electrons available for bonding, we can make one of those bonds with another s p 3 hybridized carbon, so we're going to make up one pair here.

如果键角仍然是109。,同样，我们还有4个未配对的电子可以用来成键，我们可以用其中的一个,和另外一个sp3杂化碳原子成键，这样我们可以组成一对。

If I pick an angle of 60 degrees, these are some numbers like half and root 3 over 2.

要是我选择一个 60°的角,上面的系数就会是二分之一和二分之根号三

If its in Cartesian form I'll pass in an x and y and compute what a radius and angle is.

来得到的这个点,我都可以得到这个点的,全部的这种信息。
