How to use a compass to take the distance between two points and use it elsewhere?
I have two points A and B ad would like to use the compass to:
- take the distance between points A and B
- make an arc with the center in a point C and a radius of the previous distance [AB]
I do not want to measure that distance (and have it in, say, centimeters) but to construct the arc based on the compass spread (sorry if this is not the right expression, I mean to use the compass to take unitless lengths between points).
Is this possible? (I am sure that it is as this is a fairly basic use for "ruler and compass" kind of constructions)
Thank you for any pointers!
