a protractor
A protractor, or a 45 degree triangle
the unit used to measure angle is degree. It is also measured in radians.
A speed square or rafter angle square is a tool that can be used as a saw guide. The purpose of this tool is to guide the saw when making short 45 and 90 degree angles.
The main difference between a 21-degree and a 30-degree framing nailer is the angle at which the nails are loaded and fired. A 21-degree framing nailer uses nails loaded at a 21-degree angle, while a 30-degree framing nailer uses nails loaded at a 30-degree angle. This difference in angle can affect the accessibility and maneuverability of the nailer in tight spaces, as well as the type of nails that can be used with each tool.

it is used as an degree. It is an unit of angle.
A protractor is used to draw a right angle of 90 degrees.
the most common angle used in constructing building is 90 degree.
A try square is a woodworking tool used for marking and checking right angles in woodworking and metalworking projects. It consists of a handle and a blade set at a 90-degree angle to ensure accurate measurements and precise angles. The try square is commonly used to check the squareness of edges, mark straight lines perpendicular to an edge, and verify the accuracy of cuts and joints.
