Example: these two triangles are similar: If two of their angles are equal, then the third angle must also be equal, because angles of a triangle always add to make 180°. In this case the missing angle is 180° − (72° + 35°) = 73°...

Before we get into any more detail, we need to cover some basic terminology that will help you understand the unique fractal properties. Self-similar All fractals show a degree of self-similarity. This means that as you look closer and closer into the details of a fractal, you can see a...
In addition to self-similarity, fractals also possess something known as fractal dimension, a measure of their complexity. The dimension is not an integer -- 1, 2, 3 -- but a fraction. For example, a fractal line has a dimension between 1 and 2. The beginnings of a Koch snowflake ...

Function: The function to derive (sin, cos, tan, cot, sec, csc) Sign: The "primary" functions are positive, and the "co" (complementary) functions are negative Scale: The hypotenuse (red) used by each function Swap: The other function in each Pythagorean triangle (sin ⇄ cos, tan ...
From the connectivity graph, a minimum spanning tree is devised that summarizes both feature spatial relationships and feature data similarity. Features become nodes in the minimum spanning tree connected by weighted edges. The weight for each edge is proportional to the similarity of th...

And fromsimilarity, ratios like “height to width” must be the same for these triangles. (Intuition: step away from a big triangle. Now it looks smaller in your field of view, but the internal ratios couldn’t have changed.) This is how we find out “sine/cosine = tangent/1”. ...
