You must show your work and support your answers by calculating slopes, midpoints, distances. For the quadrilateral with verticies J(1, 3), K(3, 1), L(3, -2), M(-2, 3):

-Verify that it is a trapezoid
-Determine whether it is an isosceles trapezoid
-Find the length of the midsegment

2) Determine whether ABCD is a rhombus, rectangle, or square: A(-2, -1), B(0, 2), C(2, -1), D(0, -4)

3) Prove that ABCD with vertices A(-3, 0), B(-2, 3), C(4, 1), D(3, -2) is a parallelogram. Then determine whether it is also a rectangle.
