Determine the lengths of the diagonals of the trapezoid with vertices

*A*(–3, 3), *B*(12, 8), *C*(7, 6), *D*(0, 7) to find if it is isosceles.

The vertices of a parallelogram are (3, 6), (9, 13), (3, –1), and (9, 6).

Sketch the parallelogram, and use the distance formula to verify that opposite sides have equal length.
