1. Given an angle PQR, describe a strategy to construct the bisector of this angle using only a compass and straightedge. Provide a sketch of this construction. Provide a deductive argument that your construction is correct.
NOTE: The compass opening needs to remain unchanged throughout the entire process. Decide the amount of opening arbitrarily and keep it unchanged throughout.
Step 1: Construct an arc from the vertex of the angle intersecting both sides of the angle.
Step 2: From each of the point of intersection, draw an arc in the interior of the angle.
Step 3: Obtain a point of intersection from the two arcs and draw a straight line passing through the vertex of the angle and the newly obtained point of intersection.
The argument behind the correctness of the construction is that the point A that we have obtained from the intersecting arcs is equidistant from the sides of the angle and so it is supposed to lie on the angle bisector.
