Conway triangle notation Conway triangle notation In geometry, the Conway triangle notation, named after John Horton Conway, allows trigonometric functions of a triangle to be managed algebraically. Given a reference triangle whose sides are "a", "b" and "c" and whose corresponding internal angles are "A", "B", and "C" then the Conway triangle notation is simply represented as follows: where "S" = 2 × area of reference triangle and in particular Furthermore the convention uses a shorthand notation for formula_14 and formula_15 Hence: Some important identities: where "R" is the circumradius and "abc" = 2"SR" and where "r" is the incenter, formula_22 and formula_23
