Problem 1: First step: You see the CIRCUMCENTER of a triangle ABC. If you move point C along the line parallel to base AC... What locus of points is created if C moves along the line parallel to the base. Do a hand draft of this locus.

Problem 2: Now point C moves along a circle (or on another curve). ......

Problem 3: Now we consider a quadrilateral (4-sided polygon) ABCD. Construct the perpendicular bisectors of the quadrilateral ABCD

Problem 4: You see CENTER OF GRAVITY of a triangle ABC. If you move point C along the line parallel to base AC... What locus of points is created if C moves along the line parallel to the base. Do a hand draft of this locus.

Problem 5: Now we consider a quadrilateral (4-sided polygon) ABCD. Construct the perpendicular bisectors of the quadrilateral ABCD
