That doesn't make sense - there is not "a" triangulum galaxy, it is "the" triangulum galaxy. In other words, this is the proper name of one specific galaxy.
The galaxy Triangulum is like the Milky Way and Andromeda galaxies a Spiral Galaxy
Two nearby galaxies are Andromeda galaxy and Triangulum galaxy. Andromeda galaxy is about 2.56 million light years away from us. Triangulum galaxy is about 3 million light years away from us.
Milky Way, M31 (the Andromeda Galaxy), the Triangulum Galaxy, the Large Magellanic Cloud, the Small Magellanic Cloud, ...
The Triangulum Galaxy (also known as M33 and NGC 598) is a spiral galaxy 3 million light-years from Earth in the Triangulum constellation, and is 60,000 light-years in diameter, and contains 40 billion stars.
Spiral galaxies
The Large Magellanic Cloud and the Small Magellanic Cloud are two nearby dwarf galaxies. Two larger galaxies that are still part of our local group are the Andromeda Galaxy (a.k.a. M31), and the Triangulum Galaxy. All of the above-named galaxies can be seen with the naked eye.
The Large and Small Magellanic Clouds, which are 2 small galaxies orbiting the Milky Way.The Andromeda Galaxy, which is slightly larger than the Milky Way.The Triangulum Galaxy, which is slightly smaller than the Milky Way.

The observable Universe has at least a hundred billion galaxies. The galaxies closest to us are part of the so-called "Local Group" (that is, the group that includes our galaxy); this Local Group includes our own galaxy (i.e., the Milky Way), the Andromeda Galaxy, the Triangulum Galaxy, and about 50 dwarf galaxies such as the Large Magellanic Cloud and the Small Magellanic Cloud. Then, of course, there are hundreds or thousands of galaxies "near-by" as distances between galaxies go, but outside of our Local Group.
