Which of the following steps is NOT part of the angle bisector construction process?

In the process of constructing an angle bisector, each step has a specific role in ensuring that the angle is accurately divided into two equal parts. The steps involved include:

• Keeping the compass the same length: This is crucial for creating two equal arcs from the angle's vertex, which will intersect the angle's sides. Maintaining the same length throughout this process ensures accuracy in determining the angle bisector.

• Drawing two arcs from the first arcs: After making the initial arcs from the vertex, the next step involves drawing arcs from the points where the first arcs intersect the sides of the angle. This creates intersection points that are essential for further steps in the construction.

• Drawing a line through where the arcs cross: This final step is important as it connects the intersection points created by the arcs, effectively drawing the angle bisector.

Marking the angle with a protractor, although useful for measuring angles, is not part of the angle bisector construction method itself. The construction relies on geometric techniques rather than measurement with a protractor, making it unnecessary for the specific task of bisecting an angle accurately. Thus, this step is not included in the correct sequence of actions for constructing an angle bisector.
