Drawing circumferences passing through points given radii

Resolución
Solución

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.
