Draw the following line segments, and then draw the perpendicular bisector of each line segment. (a) AB = 3 cm (b) PQ = 4.5 cm (c) ST = 5.5 cm (d) XY = 6.5 cm
Draw a line segment AB, 6 cm long. Draw its perpendicular bisector. Mark a point P on the perpendicular bisector 4 cm from the midpoint of AB. Join AP and BP. Measure AP. What is the length of BP? Why?
