A DNA molecule has 2 strands. Complementary base pairing is when a base on one strand 'matches/is complementary to/ fits with' the base on the opposite strand.
An easy way of remembering which bases are complementary is the word 'taxi' but instead 'TAGC'
T and A are complementary and have 2 hydrogen bonds between them
G and C are complementary and have 3 hydrogen bonds between them.
Hope this helps!
