GO DEEPER The formula P = a + b + c gives the perimeter P of a triangle with side lengths a, b, and c. How much greater is the perimeter
of a triangular field with sides that measure 33 yards, 56 yards, and
65 yards than the perimeter of a triangular field with sides that measure
26 yards, 49 yards, and 38 yards? (6.EE. A.2c)

Which statement explains how you could use coordinate geometry to prove the opposite sides of a quadrilateral are congruent? a. use the slope formula to prove the slopes of the opposite sides are the same. b. use the slope formula to prove the slopes of the opposite sides are opposite reciprocals. c. use the distance formula to prove the lengths of the opposite sides are the same. d. use the distance formula to prove the midpoints of the opposite sides are the same.
