RH

Please help! :( The coordinates of the midpoints of the sides of a triangle are A(0, 1), B(4, 0), and C(2, –2). Find the coordinates of the vertices of the triangle. Hint: You should plot out this problem using graph paper! A. (–2, 1); (2, 3); (6, –2) B. (–2, –1); (–2, 3); (5, –3) C. (–2, –2); (0, 3); (0, –1) D. (–2, –1); (2, 3); (6, –3)

    all i know is trial and error using the midpoint formula on each choices ...

    well you dont really have to make an effort, you'll see it through the coordinates

    look, for example if you'll examine letter A , the y coordinate of one of its midpoint should be 2... there's no positive 2 y coordinate in the given midpoints

    the midpoint formula is (x + xsub1) / 2 and (y + ysub1)/2 right?
