Bob gets the concept.

Once you establish the right angle you have mother point.

You extend the right angle to set the other corner post of the narrow dimension (daughter) and the first post in the long side (son).

After that it's a tape measure and string line job to lay everything else out.

Getting the mother, daughter, and son posts set correctly is critical. One of those is out and everything else will skew.

Talked to Castle Key the other day about this and it dawned on me, and no one here thought of it, either...

You make a story pole to set your poles. A very straight 2x4, a piece of iron pipe, whatever. Use it carefully and everything is set to the same distance apart.

How is that easier than laying out the 60' side first with wooden stakes and a piece of string, then marking 10' sections on the string?  Unless the 10' measure is less critical than just having them all the same; then I guess it might be.

Triangulate the first 10' corner to get a right angle, using whatever is your favorite pythagorean triple. ;)  Use a 10' string and a 60' tape measure to locate the 4th corner, then check that the diagonals are the same and make any necessary minor adjustments at that 4th corner post because that's where any errors should show up.  Mark off 10' sections again.

As we can see, there are probably as many ways of doing this as there are people laying out bocce courts.

A storey pole eliminates the creeping errors that can factor in when trying to make final adjustments before your concrete sets.

A tape flexes, kinks, bows out, all of which can throw your measurements off over distance. A storey pole doesn't.
