Today we looked at 2 sections:
Section 4.6 Touching circles considered the relationship between the radii and distance between the centres of 2 circles if they (i) touch externally or (ii) touch internally (click here).
Section 4.7 Circle touching axes considered what happens if a circle touches the x or y axes (click here).
HW: Questions from these sections. Since I am away tomorrow I hope that you will be able to continue with this work until Friday.
