Answer:
depends upon the degree of the angle
Explanation:
vertically opposite angles are always equal like
80 = 80 sum is equal to 160 degrees not equal to 90
45 = 45 , sums equal to 90 degrees ,equal to 90
30 = 30 sum is equal to 60 degrees, not equal to 90
so we can say it depends what is the no of degrees if it is 45 only we can say the vertically opposite angles are complementary angle
