Vectors with the same size and the same direction are called equal vectors .

长度相等且方向相同的向量叫做相等向量。

Once the input vectors have passed the "equal size" and "size greater than 1" tests, the heart of the algorithm is executed.

一旦输入向量通过了“大小相等”和“值大于1”测试，就执行算法的核心部分。

So, the area is approximately equal to one half of the area of a parallelogram that I could form from these vectors.

这面积，约等于平行四边形的一半，我能用向量表示它。

I've told you, if two vectors are equal, the components must match.

我说过如果两个矢量相等,那它们的分量必须都相同

You cannot have two vectors equal without exactly the same x component, exactly the same y component.

你不能说两个矢量相等,如果它们的 x 分量不完全相同,或者 y 分量不完全相同

So, suppose I tell you to add two vectors, A and B equal to C, and I say, "What's the result of adding A and B?"

假设我告诉你们将两个矢量相加,A + B = C,我问,"A 加 B 结果是什么"
