Suppose I want to do little piece of code that's going to do planar geometry, points in the plane.
好,因此我需要一些,把这些东西收集到,一起的一些方式。
Some of these questions that look very straightforward just naming the geometry, you have to remember to do the first step before you jump in and go ahead with a naming.
有些题目是十分直接的,仅仅是说出几何形状,你们要记住在说出它的形状之前,还有一步工作要做。
So an easy thing to do in planar geometry is I want to make a line segment.
在平面几何里比较容易的一件事,就是做一个线段。
And we learned how to prove the Pythagorean Theorem in Euclidean geometry, starting with the various axioms in Euclidean geometry, ba, ba-ba, ba-ba, ba-ba, ba bum.
我们都学习过,欧几里得几何中对勾股定理的证明方法,从繁杂的欧氏几何的公理开始,邦,邦邦,邦邦,邦邦
We have two lone pairs, so if we thought about what the bonds were everywhere, 5° it would be 109 . 5, but it's bent because we're only looking at the bonds, we're not counting the Lewis structures in naming our geometry, but they do affect the angles.
我们有两个孤对,所以如果我们考虑它会成怎样的键时,应该成109。,但它是折线型,因为我们只考虑成键,在几何形状里不考虑Lewis结构,但它会影响角度。
