 Problem 233 Flag »  Reply » Benjamin Bloch has made some errors in his solution to problem #233. In his solution to the angles of the plane triangle he will fine that in triangle FAP his sum of the interior angles is 180.02 deg. (180.02 deg = 180d 1m 12s, a  big error). In triangle FHP his sum is 180.01 deg. (180.01 deg. = 180d 0m 36s) and in triangle FAG he has the sum as 180.02 deg. Maybe Bloch just forgot that according to Euclidean geometry the sum of the interior angles of a triangle is equal to 180 degrees exactly. See Euclid's Elements book 1 Proposition 32. John Nolton
