Prove that the quadrilateral with vertices at (1,2), (3,6), (7,6), and (5,2) is a rhombus using coordinate proofs.

• All four sides are congruent, so the quadrilateral is a rhombus.

• The opposite angles are equal, so it is a rhombus

• The diagonals are perpendicular, so it is a rhombus

• The sum of the interior angles is 360 degrees, so it is a rhombus

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.
