The pyramid is 20.6m tall in the midpoint and the base of each face is 35m. For this part I will assign the height A, half of the base length B, and the hypotenuse, or altitude of the face of the pyramid, C. sqrt(A^2 + B^2) = approx. 29.13. Do this again to find the length of one of the diagonal edges, using the altitude (hypotenuse of previous equation) as A, half of the base again as B, and the length of the diagonal as C. sqrt(A^2 + B^2) = approx. 34. Now we have the dimensions of a face; the base is 35m, and the sides are 34. Now, to calculate angles, we can use the cosine law. A is the top point, B is the right, C is the left. cosA = (b^2+c^2-a^2)/2bc gives you approx. A=62 degrees. Then you can use the Sine law to get angle B, using the same assignments. (sinA/a) = (sinB/b) = (sinC/c). This proves that B is 59 degrees, leaving C to also be 59 degrees. Now the key point in measuring these angles is the Cosine law, which was discovered by Jamshīd al-Kāshī, so I think you should rename it al-Kashiean.
No worries about diffraction at f/14? Didn't seem to make a huge difference anyway with the PP though.
Great use of line, really draws your eye to the pyramid. I like it. And will be seeing it in, oh, about five days...

Four days, isn't it? Five days I guess, since you guys'll probably sleep for the first day you're there

Sunday, Monday, Tuesday, Wednesday, and Thursday. We arrive in Paris at about 12:20 P.M. Thursday night (EST).
Don`t worry, I have practice dodging buses on my bike in the school lot.
