Assuming that you mean not (p or q) if and only if P ~(PVQ)--> P so now construct a truth table, (just place it vertical since i cannot place it vertical through here.)

False because complementary angles have a sum of 90 degrees.

It is false that a combination of rice and corn form a complementary protein food source.

Generally false. In a parallelogram, the opposite angles are equal. They could be complementary in a highly skewed parallelogram in which one angle is 45 degrees.
False If you buy it from the store than true
A linear pair are always supplementary, 180 degrees not 90.
