Which statement is always true about the measures of corresponding angles?
kiruha [24]

The answer is B.

complementary means adding upto 90 degrees, but they dont unless they're both 45 degrees, so its not A.

they are not supplementary because that means they add up to 180 degrees and they dont unless theyre both 90 degrees, so its not C.

there IS a relationship between the measures of corresponding angles, so its not D.

the relationship between them is that they are always the same, so the answer is B.
