When a draftsman draws three lines that are to intersect
Chapter 1, Problem 111(choose chapter or problem)
When a draftsman draws three lines that are to intersect at one point, the lines may not intersect as intended and subsequently will form an error triangle. If this error triangle is long and thin, one estimate for the location of the desired point is the midpoint of the shortest side. The figure shows one such error triangle. (a) Find an estimate for the desired intersection point. (b) Find the length of the median for the midpoint found in part (a). See 99
