In figure 3, swap 1 for 2, 2 for 4 and 3 for 6. I have a diagram that shows three circles not overlapping, the radii are 2cm, 4cm and 6cm (XYZ). There is a triangle formed by joining the centres of the circles. Prove that X = 90 degrees. Calculate Y and Z. Last edited by skipjack; November 13th, 2016 at 11:12 PM.

Are then circles tangent to one another? Can you post the diagram?
