Which of these island groups is at the corners of a Polynesian Triangle, in a region of the Pacific Ocean?

The Polynesian Triangle is a region of the Pacific Ocean with three island groups at its corners: Hawaii, Easter Island and New Zealand. It is often used as a simple way to define Polynesia. Outside the Polynesian Triangle, there are traces of Polynesian settlement. Polynesia is made up of more than 1,000 islands scattered over the central and southern Pacific Ocean. It comprises approximately 300,000 to 310,000 square kilometres (117,000 to 118,000 sq mi) of land. Out of which more than 270,000 km square (103,000 sq mi) are within New Zealand. The Hawaii archipelago comprises about half the remainder of 28,311 km square (10,931 sq mi). Easter Island has an area of 163.6 km square (63.2 sq mi).

Hawaii is composed of 137 volcanic islands built by hotspots. Easter Island is a special territory of Chile. It is famous for its nearly 1,000 extant monumental statues, called ''moai'' which are monolithic human figures carved on Easter Island between 1250 and 1500. New Zealand is the unsubmerged portion of the largely sunken continent of Zealandia, which is an entirely submerged mass. The oldest rocks in Polynesia are found in New Zealand and believed to be about 510 million years old. The oldest Polynesian rocks of 80 million years old outside Zealandia are to be found in the Hawaiian Emperor Seamount Chain.
