comment Drawing a circular arc between two rays
Option 1b: Clipping and then \node[draw] at (A) [circle through=(P)]{}; (The math is the same, just the interface is different.) Needs the through library, though.

comment Is there a way to have LaTeX perform distribution?
Don't expect it to work with non-integer numbers. TeX is not good at math.

comment Name of shapes defined in an array
By the way, \pgfmathparse{<stuff>}\pgfmathresult can otherwise shortened to \pgfmathprint{<stuff>}. (There's also \pgfmathprintnumber.)

comment Name of shapes defined in an array
A slightly different approach for method two with the evaluate key: \draw[evaluate={\first=\stC[0]; \second = \stC[1];}] (\first) to (\second);

comment Style stored in command
I recommend [style/.expand twice=\csname type#1\endcsname] for cases where \type#1 contains more than one key. (However, I wouldn't replace the key-value system with macros to begin with.)

comment Using dynamic bounds in a tikz \foreach
\numexpr only works with integers! \foreach does not evaluate the contents when looping, so it sees in {-2.25, (-2.25 + 0.5), ..., 2.25} where it cannot match the ... correctly (until right after, \foreach sees only text). You will need to evaluate \firststep before it enters \foreach. \pgfmathsetmacro\firststep{…} would be the PGF-way to do this. — Related: Q36713, Q110962, Q142188, Q244753.

comment Why isn't my TikZ line straight?
Why should they overlap? AB has a slope of 4/5, CB of 5/6, and AC of 1/1. The three points do not lie on one straight line, don't they?
