netween a sloping side and the base is I was trying to calculate
the angle between two sloping sides. My formula is It took a
page of algebra to get to this. I'll post it if you ask nicely.
My expression is much more complicated. Using your formula and
with a = 4 and h = 3.265986 (which will make a regular pyramid =
tetrahedron ) I got cos AGC = -5.9375 which is not possible! I
used my formulas and got angle = 70.528779 which is the Wiki
value. How did you get your expression? I'll check your working.
Can you prove me right or wrong when i say: cosAGC
1-6h^2-2a^2)dvide by (a^2) Hi bob? I did follow your work. The
last part is like ok, but how u came to get GC, i didn't get it.
(iii) Find point G on VB so that CGV = 90 Second diagram shows
true shape of VBC (iv) The required angle is AGC AG = GC AC = a
