## triangle alpha-beta-gamma, where alpha+beta+gamma = 120 degrees
##
## You can change alpha, beta, and gamma using 'tessellation sliders' in the geometry experiments menu.
##
## You can choose all three angles. Sliders are not allowed to change the structure of the map,
## so if they do not add up to 120 degrees, they will not match.
