Hi IneedHALP,
Thanks for interacting with me :)
There is one when they are both on the SAME side of the tangent.
and there is one when the are on OPPOSITE sides of the tangent.
draw IT ! AND you will see.
Do you know what all the words mean? Like tangent and radius?
1) Draw the tangent first. (That is just a line)
2) Now put the point H on it.
You need two pics. When when the circles are both on the same side.
and on opposite sides
draw it and work out haw far apart the centres are.
Note: a tangen is a line that only just touches the circle. It only makes contact in one place.
