Draw line segment ab. describe in your own words how you would construct a perpendicular bisector to segment ab.

To construct a perpendicular bisector of a line secment AB. Place a compass at the center of line AB and make an arc at both ends of line AB. Place the compass at each of the arcs you made at both ends of AB and make a mark above and below line AB. Join the points of intersection of both arcs above and both arcs below line AB. That is the perpendicular bisector of line AB.

7p=14 so then you would divide by p=2
