Triangulation Concepts and Tools
What is triangulation? How do you go about it? And why it is important for genealogy.
The best way to describe it is triangulation allows you to confirm your ancestors or ancestral lines when you are able to match with at least two other people who have their trees posted and you share a great grandparent (usually third cousin or fourth cousins) on the same reasonably sized segment of DNA.
With this you can identify a common ancestor or ancestral couple who has passed that segment of DNA to all of the people who match on that segment of DNA.
