ABSTRACT

Short cut in constructing angles from  to  as new development is having the capacities, such that if carefully and effectively used in our schools and colleges will go a very long way to improve the teaching/leaning of the topic and enable students perform better in mathematics in both internal and external examinations. We still need to use ruler and a pair of compasses only, as usually directed by examination bodies, though with few of the old ideas, but totally side-tract the ideas of bisecting some noted angles in order to obtain others .The fact that if you do not construct some angles and then bisect them you can not get the required ones and that only few angles can be constructed are totally erased. In this method, all angles are taking care of in the same way (equality for all angles constructions). Some angles with their diagrams are used as examples to demonstrate the method.

Keywords: Construction, Angles, Bisecting, Ruler, Pair of Compasses.
