EXERCISE 1: Draw circles with the given radii R1 and R2 passing through points A and B .
1 We take the measure of the radius R1
with the compass and translate it.
2 With centres A and B, we draw
two intersecting arcs.
The point where they meet is
the centre C1.
* The process is similar with the radius R2.
** Note that two circles can be found with
each radius.
