... Triangle area is proportional to excess of angle sum. Surface area of unit sphere = 4π Surface area of hemisphere = 2π Surface area of lune of angle A = 2A When a third line is drawn, a triangle ABC is formed. The angles at B and C mark two other lunes of area 2B and 2C, respectively. The triangle ...
