The "Right" Right Triangle on the Sphere
Dickinson, William; Salmassi, Mohammed
College Mathematics Journal, v39 n1 p24-33 Jan 2008
The question explored here is whether having a 90[degrees] angle is the most fruitful analogue in spherical geometry to right triangles in Euclidean geometry. A strong case is made for the property of a triangle with one angle equal to the sum of the other two.
