Constructing a Perpendicular Bisector Share your thoughts with the class. Was the presentation clear enough? Do you think using the virtual compass and straight-edge would be as effective for tactile learners as the actual, physical items?

Solution

In this video the virtual compass have a problem with pointing the exact point from which we should take the radius of the circles.

We need to take a line AB and we will construct a perpendicular bisector for this line. For this process we need a compass(a real one) and then point the compass on A and take a radius more than (AB/2). then make a circle. take the same measurement and make a circle from point B as well as. Then connect the two point which is the intersecting points of the two circle. suppose the point above is C and below is D. Then connect C and D. Now we have the perpendicular bisector CD for line AB.
