Up is due north, right is due east. The black lines show his path from point A to point B. The green line AB shows the shortest distance from point A to point B.Draw in the following red lines: The shortest distance, AB, is the hypotenuse of right triangle ABC. By the Pythagorean theorem, ABē = ACē + CBē, and CB = 9km + 15km = 24km ABē = 32ē + 24ē ABē = 1024 + 576 ABē = 1600 AB = √1600 AB = 40km Edwin
