A half-circle protractor marked in degrees (180°). A protractor is a measuring instrument, typically made of transparent plastic, for measuring angles. Some protractors are simple half-discs or full circles. More advanced protractors, such as the bevel protractor, have one or two swinging arms, which can be used to help measure the angle.
T bevel with protractor and dividers In use. A sliding T bevel, also known as a bevel gauge or false square [1] is an adjustable gauge for setting and transferring angles. . Different from the square, which is fixed and can only set a 90° angle, the sliding T bevel can set any angle and transfer it on anoth
The protractor head has a flat reference edge which is attached to an adjustable 180° protractor or (sometimes called a turret) with a graduated scale in both directions for reading both the angle or the complement angle. [1] The protractor head sometimes includes a small spirit level. [4] [2]
Mitre bevel A mitre bevel is an historic mitre square of a similar design to the Melencolia try square. [15] Mitre square: A mitre square is used in woodworking to mark and measure 45° angles and its supplementary angle, 135°. The most common type (pictured) has a tongue set at 45° to the stock.
The internal works of a mechanical dial indicator are similar to the precision clockworks of a mechanical wristwatch, employing a rack and pinion gear to read the probe position, instead of a pendulum escapement to read time. The side of the indicator probe shaft is cut with teeth to provide the rack gear.
Proper use of angle gauge to count in trees Angle gauge indicating a tree to measure for a basal area factor of 10. An angle gauge is a tool used by foresters to determine which trees to measure when using a variable radius plot design in forest inventory.

Using a try square to mark lines perpendicular to the edge. Using a try square to check if the full length of a board is square. The stock is usually held against the edge of the workpiece and either side of the tongue is then used as a straight edge for making a mark, or as a reference to check the accuracy of an angle.
