The instrument which has all the features of try-square, bevel protractor, rule and scriber, is Combination set.
The combination square set is a measuring tool which is designed primarily for measuring angles and lengths.
It is used by people working in a number of different trades, including woodworkers and engineers.

slip gauges are a system for producing precision lengths. The individual gauge block is a metal or ceramic block that has been precision ground and lapped to a specific thickness.

A progressive limit gauge that serves to determine whether the measured part is within prescribed limits of tolerance.
A progressive limit gauge has 'Go' and 'Not go' member on the same side of the gauge.
