Need to get the base in. Second thing I want to do, I need to get the height, so I'm going to input a value for the height, also as a float, a floating point.

也就是输入底的值，第二件我想要做的，事情就是得到三角形的高,因此我会输入一个值作为三角形的高，同样也是一个浮点数。

So what we'll have here is a trigonal planar case, and you can see that we only have three electrons that are set for bonding, so we'll add three hydrogens, and for b h 3, we'll get a stable structure here.

让电子劲量远离的时候，不用考虑它,这个例子是平面三角形，你可以看到，只有3个电子可以成键。

One is that you're supposed to eat a variety of foods and then the foods are put into different sized triangles here, depending on how much of them you should be eating.

一是你得吃多种不同的食物,各种食物也被分划在不同大小的三角形中,每个三角形的大小取决于你该吃多少

The thing is for these sorts of experiments there is a lot of control, so something that's a square in one movie will be a triangle in another movie; something that's on the top in one movie will be on the bottom in another movie.

此类实验需要控制许多因素,来保证某物在一部影片中以正方形呈现,而在另一部影片中以三角形呈现,某物在一部影片的上方呈现,而在另一部影片的下方呈现

So if you picture, for example, b h 3, it's going to look like this.

如何使键劲量相互远离，我们会有平面三角形的情形，如果你想象。

So if I were to solve this problem, here's the way I would do it. I would say, first thing I want to do, is I want to input a value for the base as a float.

如果我想要解决这个问题，这就是我要解决它的方式了，第一件我要做的事情就是要,输入一个浮点数作为三角形的底。

So again, if we think about that shape of that carbon atom, it's going to be trigonal planar, 120° it's going to have bond angles of 120 degrees, because we have this set up of having three hybrid orbitals.

如果我们考虑碳原子的形状，它是平面三角形，键角是，因为我们有这三个杂化轨道。
