Constructions of Angles without Using a Protractor Constructions of Angles without Using a Protractor Azim Premji University > University Publications > At Right Angles · Nov 16, 2022   Most students enjoy the topic of geometrical constructions using compass and ruler. When it comes to constructing specific angles, we consider only multiples of 15°. Students wonder: what about angles such as 10°, 20°, 40° and 50°? Can we construct these too? In this article, we consider this problem and offer an approximate procedure which yields angles that are reasonably close to the desired measure. So, the solution that we give is not exact. It is assumed that the student knows: (i) how to construct a 60° angle, (ii) how to divide a line segment in a given ratio, using compass and ruler only. I know you all are very curious to know that how these angles will be constructed without using protractor, so to read full article c lick on the link to read published part:  https://publicatio...
