Both these regions are polar regions/ zones.
Polar regions are the areas of the globe surrounding the globe also known as frigid zones. The Northe pole and the South pole being the centres, these regions being dominated by the polar ice caps, resting respectively on the Arctic Ocean and the continent of Antarctica.

They only live together in zoos; in the wild, polar bears live in the Arctic (north) and penguins live in the Antarctic (south).
All the Christmas cards and movies showing penguins frolicing with polar bears are wrong. Penguins are found only in the Southern Hemisphere and polar bears are found only in the Arctic regions of northern Canada and Europe. Five species breed in Antarctica and others live in Australia, Africa, and South America.
These are both polar regions.
Because penguins are found in Antarctica (South Pole) and polar bears are only found in the Arctic (North Pole).
Those are the "polar" regions.
