Bi means two
Sect means to cut
Bisect means to cut in two
A line that divides another line segments in half and has right angles to it.
1st way to make a Perpendicular Bisector:
Fold the paper, so point A is on point B. Draw a line in the crease that you made. Label it C,D. Where they intersect, label it P.
2nd way to make a Perpendicular Bisector:
You have to use a Right Triangle.
Draw a line segment on a piece of paper with a right triangle.
Use the right triangle to find the half mark of the line segment.
Draw another line segment on the half mark, intersecting with the original
Make sure that it is 90 degrees. (use a protractor to check)
3rd way to make a Perpendicular Bisector:
Use a Compass.
Make an arc from point A that is greater than half way.
Make an equal sized arc from point B.
Connect the arc intersection with a straight line.
