LMNP is a parallelogram.

On a coordinate plane, parallelogram L M N P is shown. Point L is at (negative 4, 1), point M is at (2, 4), point N is at (3, 2), and point P is at (negative 3, negative 1).

What additional information would prove that LMNP is a rectangle?

Show that one interior angle is a right angle. For example, prove LM ⟂ MN.

Compute slopes: slope(LM) = (4−1)/(2−(−4)) = 3/6 = 1/2 and slope(MN) = (2−4)/(3−2) = −2. Their product (1/2)(−2) = −1, so LM ⟂ MN. Since a parallelogram with one right angle is a rectangle, LMNP is a rectangle.
