Answer:
see explanation
Step-by-step explanation:
The diagonals of a parallelogram bisect each other.
Thus CO = OA = a
(a)
CA = CO + OA = a + a = 2a
(b)
AB = AO + OB = - a + b = b - a
(c)
BC = BO + OC = - b - a
Answer:
(a) CA=CO+OA=a+a=2a
(b) AB=AO+OB=-a+b=b-a
(c) BC=BO+OC=-b-a
Step-by-step explanation:
a) CA=CO+OA=a+a=2a
(b) AB=AO+OB=-a+b=b-a
(c) BC=BO+OC=-b-a
