By using a protractor we can measure an angle
An angle measuring more than 90 degrees is obtuse. An angle measuring less than 90 degrees is acute. An angle measuring 90 degrees is right.
there is special instrument named "angle distribution measuring system" for the divergence angle measurement of LEDs. my email: bkk2003@163.com
You get two angles measuring 21 degrees!
The purpose of measuring taper angle is to obtain taper angle
When measuring an angle you have to measure the sides using a protractor.
