I'm desperate use δabc to answer the question that follows: triangle abc. point f lies on ab. point d lies on bc. point e lies on ac. ad, be, and cf passes through point g. line ad passesgiven: δabcprove: the three medians of δabc intersect at a common point.when written in the correct order, the two-column proof below describes the statements and justifications for proving the three medians of a triangle all intersect in one point: statements justifications point f is a midpoint of line segment ab point e is a midpoint of line segment ac draw line segment bedraw line segment fc by construction point g is the point of intersection between line segment be and line segment fc intersecting lines postulate draw line segment ag by construction point d is the point of intersection between line segment ag and line segment bc intersecting lines postulate point h lies on line segment ag such that line segment ag ≅ line segment gh by constructioni bgch is a parallelogram properties of a parallelogram (opposite sides are parallel)ii line segment fg is parallel to line segment bh and line segment ge is parallel to line segment hc midsegment theoremiii line segment bd ≅ line segment dc properties of a parallelogram (diagonals bisect each other)iv line segment gc is parallel to line segment bh and line segment bg is parallel to line segment hc substitution line segment ad is a median definition of a medianwhich is the most logical order of statements and justifications i, ii, iii, and iv to complete the proof?
