Which of the following statements is false? A. Two circles are congruent if and only if they have the same radius.
B. The product of two numbers is even if and only if both numbers are even.
C. Today is Monday if and only if yesterday was Sunday.
D. Two lines are parallel if and only if they have the same slope.

C is false

Step-by-step explanation:

Example 3 is odd but 6 is equal.

3•6 is 18

18 is even

step-by-step explanation: h: (- 3, 6)

m: (1, - 2)

o: (7, 6)

r: (- 9, - 2)

midpoint of hm: (- 1, 2)

midpoint of or: (- 1, 2)

therefore, b is the midpoint of both diagonals bisect each other !

to prove the diagonals are perpendicular, show that the product of the slopes = - 1
