11. Supplement or Complement
•Most of us will choose water over vitamin as in this case, vitamin
acts as a SUPPLEMENT whereas water acts as a COMPLEMENT.
Supplement means an extra or additional items/things whereas
COMPLEMENT means something that completes or goes very
well with something; in this case it completes your meal.
•Your slides are the same. You can choose to make you slide to be
your complement or to be your supplement. Complementary
slides mean you have to be there to explain the slides or to
rephrase; the slides need you! On the other hand, supplementary
slides mean the slides can talk on its own. Your presence or
absence will not affect your slides. It didn't care!
