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.

Question

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.
Graph points are (3.0,1.7);(3.1,1.9);(1.8,1.5)

*A)Find an estimate for the desired intersection point.

​*B) Find the length of the median for the midpoint found in part (A)

Steve · Answer

so, what is the shortest side? Then find its midpoint. Just use the distance formula, and recall that the midpoint's coordinates are the average of the endpoints' coordinates.
