Clive,
I did the math on this... I was noticing an anomaly... so you can ignore my previous math.

If you are facing the pyramid at a 45 degree angle, so that the diagonal becomes the base... then the triangle is 43.385-43.385-93.23 based on the petrie survey.

We aren't viewing the pyramid from a 45 degree angle, so the base of this diagonal is reduced, moving it close to 90 degrees... and this was the anomaly I picked up on.
****
On a side-note, if G2 had been 290 cubits tall, then the triangle would have been 45-45-90.
