Sommerville and Davies classified the spherical triangles that can
tile the sphere in an edge-to-edge fashion. Relaxing this condition
yields other triangles, which tile the sphere but have some tiles
intersecting in partial edges. This paper determines which right
spherical triangles within certain families can tile the sphere.
