Measurement or measure of a complex number?

Question

In math, do we write "measure of an angle of two vectors" or "measurement of an angle of two vectors"?

I would say "measure of the angle between two vectors." – user317176 May 14 '22 at 01:49 — user317176, May 14 '22 at 01:49

The correct way to say that is "measure of the angle between two vectors", note that "the" is important since it isn't an arbitrary angle between the two vectors, we consider the convex angle ($0\leq\theta\leq\pi)$, so it is only one. Measurement sounds more like a physical thing in my opinion, so measure fits better in here.
