Angle bracket

Description

14 cm square.  Far from being just another square, this one is a real innovation: not only are the graduations on both sides, but they also start at the tip. The error of a few millimetres when drawing curves is a thing of the past (an experience corroborated by many secondary school pupils). The second trick is to use the hypotenuse as a protractor from 0 to 90°. The measurement is more precise than with a small protractor, because you measure over 10 cm and not 4 cm. Finally, the graduation in degrees for angles is doubled by a graduation in radians. Everyone knows degrees, but the standard (ISO) measurement for angles is the radian. This introduction to radians will make it easier to use when dealing with scientific calculations. A memory aid for the value of Pi (3.141592 … ) and a radian/degree correspondence table complete the information. Made from shatterproof material, these brackets are more resistant to shocks. However, they are still rigid enough to maintain the precision required for school work (marshmallow squares that can be twisted and distorted in all directions are less rigorous). These squares are more resistant to the many and varied stresses of school and should last for more than one school year. A small saving is always worth making. Made in Italy
