A family friend said he looked the Pyramids as well, and suggested that they probably had several notable uses, but most of all they were a set of prospecting and land surveying compasses.

For example, at any point around the Valley of Kings in Egypt, all the tombs are scattered in craggy rocks and ravines. There appears to be no indication how they ensured one grave plot didn't intersect with another's grave plot. This applies to any land plotting, not just the graves, mind you.

By having a large pyramidical structure amidst the valley, which you can see from any decent vantage point, you can calculate the surface area of each side of the pyramid and discern your relative location depending on the ratio of one triangle's visual surface area compared to the other.

As you physically move around the pyramid, you get a different perspective and one side of the pyramid grows in relative area while the other shrinks. Set up a stand that holds a paper in front of the pyramid, trace around the white limestone that used to be on the pyramid and would pierce through the translucent papyrus, and then calculate the surface areas of each triangle. Take the ratio, and you know the exact radial degree you are from the pyramid's center-point, the Keystone on top.

You can calculate the distance, then, by comparing the ratio of size between two or more of the pyramids.

Then, knowing the direction of the sun gives you a North, South, East, and West direction as well as knowing the relative location to the Nile, and BAM, you can pinpoint exactly where you are relative to the Pyramid.
