What is a protractor and compass?
A protractor is an adjustable tool that typically gives a measure in degrees and in radians. It can be used to effectively measure angles and it can be used in the construction process to achieve the desired angle. Protractors can be manual or they can be magnetic. Magnetic protractors have an easy to read dial and an adjustable angle pointer that is ideal for scoring, deep cutting, or other heavy duty applications. The compass is a separate tool that can also be used to measure angles and lengths. A compass can be opened wide, but has no measurements on it. Geometric compasses are drawing instruments used for drawing circles and arcs. It has two legs, one with a point and the other with a pencil or lead. The point can be placed in the center of the circle and the pencil can be adjusted to draw the proper size circle. You can adjust the distance between the point and the pencil to adjust the size of the circle. HomElectrical has several selections of protractors and compasses to aid in construction projects.
