Summary
editDescriptionWulff net central angle 2.jpg |
English: Measuring the central angle between two points P1 and P2 on a stereographic projection using the Wulff net. A transparent sheet has been tacked in the middle of a Wulff net and the points are drawned on the transparent sheet.
The transparent sheet has been rotated until both points P1 and P2 lie on the same meridian (see Wulff net central angle 1.jpg). The angle is measured by counting the graduation along the meridian between both points (here, 2° steps: the angle is 92°). |
