ISOGG wiki entry for Triangulation
Triangulation
- When three people all match each other at the same autosomal DNA location we call it Triangulation.
- From ISOGG: "If you have at least three people with a common ancestor matching on the same segment then you can infer that the segment came from that ancestor. "
- Inversely, if three people all match each other on the same segment then you can infer they have a common ancestor.
