universal bevel protactor is an angle measuring instrument which measures acute angle ,obtuse angle as well as it is used to layout an angle. its least count is 5 minute.
5 min
The least count of a vernier bevel protractor is typically 5 minutes or 0.083 degrees. This means it can measure angles with an accuracy of 5 minutes or 0.083 degrees.
It is 5 mins. Formula : Smallest Division on Main Scale / Number of divisions on Vernier Scale = 1 degree / 12 = 60 mins / 12 = 5 mins.
