 Euclid gives exact angle bisection as a geometric construction, but he provides no computational framework for evaluating the sine of the bisected angles.

-Any angle can be bisected with compass and straightedge, yet — with a few exceptions — their numerical values cannot be derived from Euclid’s axioms or propositions.
