Consider the following statement. There are real numbers a and b such that a + b = a + b . To prove the statement, it suffices to find values of a and b that satisfy the property. Show that you can do this by entering appropriate values for a and b in the box below, as an ordered, comma-separated list of two numbers. (a, b) = Correct: Your answer is correct.

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.
