Perpendicular Bisector of a Line
- Mathew Purser
Basic Construction 2
Perpendicular bisectors are lines that are perpendicular to another line at that line's midpoint. Once we learn how to perform this BC we will unlock a new tool that will do this for us! Because we need the midpoint of the line too, we actually get the midpoint of line for free with this construction too!
Use the tools provided to bisect line AB, this means find the midpoint then draw a line at a right angle through this point. Remember, we can't guess and constructions have to be precise. Also, once you make your drawing, you should be able to drag A or B and the line will stay a perpendicular bisector. Remember, circles are great ways to draw equal lines. Try to draw the perpendicular bisector on your own but if you need help, watch the video provided.
