    agree with Dan GN = AN HN bisector so angle HNA = 45

    To measure angles start at C go anticlockwise CNH = (90 + 45) = 135 CNE = -90 the arc is the ratio of measure of the angle with circumference of the circle. the length is always positive. 135 + 90 = 225 arc HBE = HBC + CDE HABCD is a straight line 180 and DNE = HNA = 45 so DE = 45 HABCDE = 180 + 45 = 225 angle/360 = length of arc/2*pi*r different views of the same diagram same principle
