A protractor is also referred to as a transporter or gauge and it is a simple measuring device for applying or for determining angles. The gauge will certainly be found in some sort of secretary. The protractors are often integrated in drawing triangles or in geodraces. They are used to map the measured points, to measure the angles in crafting and also in school use in mathematics lessons. It should be noted that the integrated protractors are usually not as accurate with the Geodreieck. For the more accurate protractors there is a swivel rail with a scale and this has been divided into millimeters. At the desired angle, the rail can be determined. By the way, some of today's tools are already several millennia old and have their origins far before Christ's birth. What began earlier with a hand ax is today a protractor, a rotary grinder or a hammer drill. The Protractor made a name for himself in engineering and science, and he had to go through many tests before he hit the shelves inside the stores.

Everything for the garden: protractor Video Guide

The protractor is a very common tool for architects, scientists, engineers, designers and construction managers. With the help of the tool finally the precise calculations can be made. A protractor is not only important when designing larger vehicles or new buildings. Even in practical and theoretical work around statics, mechanics, physics and mathematics, a protractor can be one of the standard devices. Each protractor is of course very handy and it can be used in many ways. Many know the protractor even from the school days at the gymnasium or at the secondary school. Everyone could slowly approach the features and functions of the protractors here. He was used here for simple drawings and constructions and in physics and mathematics lessons he became a constant companion. The small tool, however, is more like the simple instrument where angles can be read or adjusted. Not just analogously, the angle measurement can be performed today. There are also many digital goniometers for everyday use. Especially at the larger scale, the model makes very good in the measurement of entire buildings and rooms. In use, most models are very easy to handle and usually they are not very significant. For a protractor you no longer need the simple design of three or two components where a scale was applied. The division of 180 degrees is most commonly found on the protractor. There is the circular arc labeled with a scale and it is on the horizontal line. In addition, there are the full circle angle, where the angle can be removed from 0 to 360 degrees. There are electronic goniometers as high quality devices for architects and craftsmen. In addition, there are also laser protractors for an accurate measurement of cavities and vaults. The simple models are already available for a few euros and they offer simple plastic. There is of course a low weight and so they can be taken anywhere. At construction sites protractors have to endure more and here there are then the protractor made of wood or metal.
