Is the following definition of complementary reversible? If yes, write it as a true biconditional.

Complementary angles are two angles whose sum measures to 90°.

The statement is not reversible.

Yes, if angles are complementary, then their sum measures to 90°.

Yes, angles are complementary if (and only if) their sum measures to 90°.

Yes, angles are complementary if their sum measures to 90°.

Answer 1

2nd option is correct

angles are complementary if and only if they sum to 90 degrees

p iff q

q iff p

it's a biconditional relation

with the arrow pointing in both directions between p and q

Answer 2

Two angles are complementary if and only if the sum of their measures is 90°.
