The Polynesian Triangle is a region of the Pacific Ocean anchored by three island groups: Hawai'i, Rapa Nui ( Easter Island) and Aotearoa ( New Zealand). The many island cultures within the Polynesian Triangle share a similar proto- Malayo-Polynesian language used in Southeast Asia 5000 years ago. Polynesians also share identical cultural traditions, arts, religion, sciences. Anthropologists believe that all Polynesians are related to a single proto-culture established in the South Pacific by migrant Malayo people.
