Author:Sabrina Cook, Tim Brzezinski

G.1.3.3 Video: What is a perpendicular bisector?

Play with this applet to explore the concept of Perpendicular Bisector. Slide the black dot that says "Slide Me Slowly!" VERY SLOWLY!

Summarize video G.1.3.3 - what did you learn?

Given two points, A and B, all the points that are equidistant from both A and B form a line. What is true about that line? Select the best answer.

Select all that apply

A
All the points on the line are equidistant from both point A and point B.
B
The line is perpendicular to segment AB.
C
The line goes through the midpoint of segment AB.

Use the construction tools to create segment AB. Then try to figure out how to find the Perpendicular Bisector of segment AB. We haven't done this before, so just play around and try to figure something out!
