... Stage 2'. Suppose the triangle A'BC is obtained from ABC by orthogonal projection on a plane through BC. If A'BC is Ramsey, then so is ABC. Note also that if ß' and ß (7' and 7) are the angles at B(C) in the two triangles, respectively, then tan 7/ tan ß and tan 7'/ tan ß' are equal. This makes poss ...
