In this article, in order to help you stdy maths, we will explain what is a bisector and how to construct the bisector of and angle.
To understand what is a bisector, first of all is necessary to understand what is an angle. An angle is the area bounded by two rays with the same origin. Thus, it is an angle formed by two sides (rays) and an vertex (the point of origin of the rays).
The bisector is a ray with the same origin as the angle, which divides the space into two equal spaces. Thus, if the angle have a amplitude of 40°, the angle bisector will divide this into two angles with an amplitude of 20.
Below you can find a video on how to construct the bisector of an angle.
