Re: spherical geometry (was Re: navigation riddle)

Here's the outline:

1) The legs of the triangle are by definition geodesically
2) That means each leg is a piece of a great circle, since
we are dealing with a spherical world.

Wait a minute.

Didn't we begin by walking East a mile or so from a pole?

That's not a Great circle.

When did I miss a turn off track?
