CONSTRUCTION OF ANY ANGLE WITHOUT PROTRACTOR

Geometry is one of the foremost significant chapters in mathematics. The construction of angles is one of the important topics of geometry. In geometry, the term construction refers to the precise sketching of shapes, lines, or angles using mathematical instruments. To construct angles, all you'll need is a compass, a ruler, and a pencil, as well as a protractor to measure the angles you've constructed. As there are no numbers involved, this is the simplest type of geometric building. We can only draw some special angles without using a protractor, such as 30, 60, 90, 120, 180, and non-special angles with 1 degree deviation from the needed angles, such as 83, 72, 68, and so on. In our lower secondary school, the method of constructing special angles is commonly taught. We can, however, draw any angle between 0 and 360 degrees using the approach we devised, with no variation from the needed angle. Construction of angle is essential in math because it may be applied to the construction of other geometric shapes, particularly triangles.
