How do you construct a perpendicular bisector

ms sue please help :)
Sorry, I don't remember. I haven't done that in about 65 years.

It uses a compass and a pencil.

Google is a big help!

google is your friend. I can tell you how, but you can find many illustrated instructions online.

Place compass at one end of line segment. Mark an arc with radius more than half the line length.

Do the same at the other end.

Make sure the arcs are long enough to intersect in two places.

Draw a line connecting the two intersection points. That is the perpendicular bisector of the first line.
