Opposite angles are equal. Thus a=d and f=g, here we can see that d and f are complimentary angles, which sum is equal to 180. Hence, on adding a,d,f,g, the sum must be 360.

Here for the given question, we will use the Opposite angles equal property. we can see that, a=d and f=g Also, d and f are complementary angles, which have a sum equal to 180. ( d + f = 180) Also, a and g are exterior angles with a + g = 180 Thus, (a+g) + (d+f) = 180 + 180 = 360 Hence, on adding a,d,f,g, the sum must be 360.
