Use δabc to answer the question that follows: given: δabc prove: 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 point e is a midpoint of draw draw by construction point g is the point of intersection between and intersecting lines postulate draw by construction point d is the point of intersection between and intersecting lines postulate point h lies on such that ≅ by construction i bgch is a parallelogram properties of a parallelogram (opposite sides are parallel) ii ≅ properties of a parallelogram (diagonals bisect each other) iii and substitution iv and midsegment theorem is a median definition of a median which is the most logical order of statements and justifications i, ii, iii, and iv to complete the proof?
a. iv, ii, iii, i
b. ii, iv, i, iii
c. iv, ii, i, iii
d. ii, iv, iii, i
