Beam OC – bisector of angle AOB and angle AOC = 45 degrees. Determine the degree measure of the angle AOB.

Let us calculate how many degrees the AOB angle will correspond to if we know, based on the conditions of this task, that the degree value of the AOC angle, which was formed when dividing the AOB angle by the OC bisector, is equal to 45 °:

2 * 45 = 90.

Answer: The angle AOB is 90 °, that is, it is right.
