Here is a way to find the distance across a gorge using a carpenter's square and a five-foot pole. Plant the pole vertically on one side of the gorge at point A and place the angle of the carpenter's square on top of the pole at point B, as shown in the figure. Sight along one side of the square so that it points to the opposite side of the gorge at point P. Without moving the square, sight along the other side and mark point Q. If the distance from Q to A is 6 inches, calculate the width of the gorge in feet. B L" A 5' The width of the gorge is (gorge) feet P
