Question

what is angle bisector and how can we draw it
​

Answer 1

Answer:

An angle bisector is a line that bisects or divides an angle into two equal halves.

Step 1: Span any width of radius in a compass and with O as the center, draw two arcs such that it cut the rays OA  and OB at points C and D respectively.

Note that OC = OD, since these are radii of the same circle.

Step 2: Without changing the distance between the legs of the compass, draw two arcs with C and D as centers, such that these two arcs intersect at a point named E (in the image).

Note that CE = DE, since the two arcs were drawn in this step was of the same radius.

Step 3: Join the ray OE. This is the required angle bisector of angle AOB.
