9-64 A. Starting with a smooth, square piece of tracing paper, find a way to create parallel lines (or creases). Make sure the lines are exactly parallel. Be ready to share with the class how you accomplished this. B. With a new piece of tracing paper, trace line segment AB at right. Use your straightedge for accuracy. Can you fold the tracing paper so that the resulting crease not only finds the midpoint of ABbut also is perpendicular to AB? Remember that this is the perpendicular bisector of AB. Prove that your crease is the perpendicular bisector. C. On the perpendicular bisector from part (b) above, choose a point C and then connect AC and BC to form triangle ABC. What type of triangle did you construct? Use your geometry knowledge to justify your answer. D. In part (b), you determined how to use tracing paper and a straightedge to construct a line that bisects another line. How can you construct an angle bisector? E. Did you know that the angle bisectors of a triangle intersect at a single point? On your tracing paper, connect BC to form triangle ABC.Then fold to find the angle bisectors of the other two angles,
