Notation

$z^*$ is the complex conjugate, $|z|$ the modulus, and $\arg z$ the principal argument unless otherwise specified. Re/Im are Argand axes; some original figures call them x/y. All geometric constructions use the same coordinates and constraints. Parametric illustrations label their chosen values; the formulas state the general case.
