D) The relationship cannot be determined from the information given.




Using Exterior angle property:
b = a + c' and c = a + b'

Col. A: 180 + a
Col. B: b + c

Col. A: 180 + a
Col. B: (a + c') + (a + b')

Col. A: 180 + a
Col. B: 2a + b' + c'

Subtracting a from both:

Col. A: 180
Col. B: a + b' + c'

Since, sum of all interior angles in a triangle is 180

Col. A: 180
Col. B: 180

Col. A = Col. B
Hence, option C
