If you have tested with AncestryDNA, 23andMe or Family Tree DNA's Family Finder then please read:  Triangulation for Autosomal DNATriangulation: Proving a Common AncestorBenefits of Triangulation and How to Triangulate.

Triangulated Groups* inherited their shared segment from their shared ancestor. Invite all your DNA matches to add their ancestry to WikiTree, or ask their permisson to add their ancestry here for them.  WikiTree's Relationship Finder reveals the shared ancestral couple(s) of a triangulated group.  If there is only one shared ancestral couple then mark each parent / child relationship on each ancestral line back to the shared ancestral couple as Confirmed with DNA and add citation (e.g. for a mother child relationship:

"Maternal relationship is confirmed by a triangulated group consisting of Peter Roberts GEDmatch F008867, Kris Sjostrom GEDmatch A936004 and Elizabeth Collins GEDmatch FE16264 sharing a 10.8 cM segment on chromosome 1 from 163621974 to 173712569."

*Triangulated Groups are 3 or more people all matching each other on the same segment.

Thanks Peter, I have not tried that feature.

I've been using the Wikitree consolidated tree in my initial contact email to triangulated groups.  You get to that tree by (from your home page) going to the 'Family Tree & Tools' tab, then clicking on the 'Compact Family Tree' link.  That brings up a terrific 8-generation family tree.  Copy the IP address and then paste that into the email you send.

I was just recently asked by a 'new cousin' why I sent people to Wikitree as opposed to my ancestry.com tree.  I told him that it was a more user friendly tree and informed him of the DNA features available with Wikitree.  He loved the idea and planned to join.

Many of my matches aren't on Gedmatch.  I have a lot of triangulated groups from FTDNA.  As such, there's no ID # to provide.  And the majority of them aren't on Wikitree either.  So I can't link to their names.  Additionally, I share different segment lengths with different people (with different start/stop points), as they do with one another.  So I don't put the segment lengths or start/stop points on my citation.  I have started listing the chromosome, although I've got segments on multiple chromosomes that trace back to the same MRCA.

http://www.wikitree.com/wiki/Barnard-1255 (Mary India Barnard) has the following three paragraphs under a DNA heading:

Several people have matched DNA and are part of a triangulated group that traces their ancestry to William Snell and Martha Dorminy. The triangulated group includes (as of 6 June 2015) three descendants of Lewis Daniel Snell and Mary India Barnard. One of them descends from Verlie, one from her sister Anna, and one from her sister Myrtle.

Maternal relationship is confirmed by four descendants of Sarah (Mary India's great-grandmother) matching their mtDNA. Two of these people descend from Sarah's daughter Nancy and two descend from Sarah's daughter Alcey.

Paternal relationship is confirmed by descendants of William Stroud Sr. and Margaret Rose (from whom Mary's father descends). Several people are sharing a segment on chromosome 9. (Posted by Darlene Athey Hill, who you may contact for additional information.)

This is a nice alternative, Darlene.

One of the great things about WikiTree is the many different ways of seeing information.  You mentioned the Compact Family Tree.  I find this tree very difficult to read and understand, so I use the alternative Surnames list, which is located farther down the "Family Tree and Tools" tab.  Here is my Surname list:  http://www.wikitree.com/treewidget/Cooper-1/10  I am the big Cooper at the top, then my parents, then their parents, etc. by generation.  I think this is a little easier for new matches to understand.  I send this link to my matches so that they can look for surnames we share in common.  That common surname(s) is where we then concentrate our search for our common DNA ancestors.  The list also  shows ? for those ancestors that are still missing on my own tree.  My match and I could have a common DNA ancestor hidden in one of  those question marks.
