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.

please review

nice simple geometry kata. I like it.

seems to be approved

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)
