2)

p = two angles are congruent supplementary angles

q = they are right angles

q → p : If two angles are right angles, then they are congruent supplementary angles.

This is ALWAYS TRUE

3)

p = c is negative and a > b

q = ac < bc

q → p : If ac < bc, then c is negative and a > b

This is sometimes true...IT DEPENDS

Counterexample: Let a = -1, c = 2, and b = 3, then ac < bc. Since c is not negative, the statement is false.
