In a piece of paper draw segment AB and its midpoint D. Then draw the perpendicular bisector of segment AB and name it line CD.

In your journal, write a proof that shows that the distance of point C from endpoint A is the same with the distance of point C from endpoint B, or in other words prove that CA=CB.

When you dilate a figure with a scale factor of 1/2, what will the dilated figure look like?                                                                                           a: the dilated figure will have side lengths that are half the length of the original side lengths.                                                                          b: the angles in the dilated figure will be half the measure of the original figure.                                                                                c: the dilated figure will have side lengths twice the length of the original.
