Points are actions – Complex Number 2

Spiral Similarity is a combination of rotation and dilation. It is an interesting geometric transformation for a variety of reasons. In the previous section, we found that any segment can be mapped onto any other segment using spiral similarity. We wish to treat...

Spiral Similarity – Complex Number 1

What is spiral similarity? Spiral similarity, for our purpose, will be a beautiful motion in the plane. It is a combination of rotation and dilation (expansion or contraction by a constant factor. Suppose AB is a (finite) segment in the plane. CD be another segment....
