Mesuring multiple angle between vectors

Hi everyone,
I’m trying to measure the angle (in degree) for each corner of this closed curve.

Here is the curves

I figured the inside angles of a polygon is 180 - “A” output of Evalute Curve?

A variation on @Rickson’s method, for what it’s worth. Uses the ratio of areas.
