(type the number ONLY)

Prove that the quadrilateral with vertices at (1,2), (3,6), (7,6), and (9,2) is a trapezoid using coordinate proofs.

• The diagonals are equal in length, so the quadrilateral is a trapezoid.

• The sum of the interior angles is 360 degrees, so the quadrilateral is a trapezoid.

• All sides are equal, so the quadrilateral is a trapezoid.

• One pair of opposite sides are parallel, so the quadrilateral is a trapezoid.

Classify the quadrilateral:

K(5, -3), L(7, 1), M(9, -3), N(7, -7)

• Parallelogram

• Rectangle

• Square

• Rhombus
