condition is not correct. meaning touching or crossing. the condition says only about touch

`colliding` it is likely to be interpreted as `touching` by some users. Why not use the more specific and mathematically correct term `intersecting`?
The intersection can be one or more points, it covers any scenario, from touching to full overlapping.

C# random tests are not guaranteed to fail this qwerty solution and this almost identical one.

Description is a bit iffy.
It took me some time to understand that with 'collision' was really meant 'touching/colliding OR overlapping'. It's not the same, imho.
Maybe it's just me. No one else seems to have a problem with that.

nice simple geometry kata. I like it.

You should mark it as a suggestion to improve visibility.

This is a good idea for a series of Kata, from simplest - collision of two circles, to hardest - general collision of two arbitrarily shaped bodies in 3d.

They're equivalent in the mathematical sense, but not in the floating-point sense. This is a permanent problem with floating point numbers.
for example, if `(r1 + r2)` is really small, the precision of its product `(r1 + r2) * (r1 + r2)` is going to be bad ... so it's better to avoid multiplications if you can in a formula like this
(i didnt look at the JS translation so it's just my guess)
