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

Thanks to all

quick angles


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.
