How would you measure the angle of the thread?

I had a 29 deg cutter already ground from another job, it didn't fit, so I dug and found out about the metric flavour. Ground one at 30 degree and presto we have a match. I also have a set of Starret rules that have 60 and 30 degree angles ground on the ends, they fit my protractor, could poke the tapered end of the rule into the tread and check the angle on the protractor.
Are both ends of the nut worn or just the end that flexes to remove the backlash?
