Question

A parallelogram has vertices E(−3, 1), F(0, 2), G(−5, 5), and H(−2, 6). What are the coordinates of the midpoint of each diagonal?

(−3.5, 2.5)
(2.5, 3.5)
(−2.5, 3.5)
(−3.5, 5.5)

Answer 1

Plot the points on a graph paper and calculate the midpoints of opposite points (diagonals)
The midpoints of
\[(x _{1}, y _{1})\]
and\[(x _{2}, y _{2})\]
is
\[((x _{1}+x _{2})/2, (y _{1}+y _{2})/2)\]
