The ground rods need to be 10 foot apart in a triangle does it matter if the wire between the ground rods are longer then 10 foot and not the same length could two be 10 foot and the third pice of wire be 20 foot?

The distance apart should be equal to or greater than the length of the rods. That said I am not aware of any code or regulations that require triad grounding. May be some telco or cell tower entities. What are you working on?

That arrangement is just a silly job spec, so I would check with the them if you have doubts about how to do it the way they want.

"You can't generalize"
I am working on a natural gas metering station. yes the ground rods need to be 10 foot or greater but is it necessary for the trench to be dug in a triangle. i don't think so but don't really know. to me the wire is insulated so the only true ground would be the ground rods and the resistance in the wire is so small i don't believe it will mater. any opinions.
So if a Triad is what you are doing then yes, a triangle shape is pretty much guaranteed if you are spacing the rods roughly equal distance apart from each other rod. What other shape do three points make right. It might be a wonky looking triangle when you are done but essentially three sided. The key to a triad is making a loop. If the conductor does not loop back and tie to the first rod then you just have three rods, not a triad.

why insulate the conductor between them?
