Step-by-step explanation:

Pangaea or Pangea was a supercontinent that existed during the late Permian period, before the Triassic.

Meanwhile, on the eastern half of the once-supercontinent, Madagascar made a break from Indian continent and both moved away from Australia and Antarctica southwards.
