Triangulum

From Slackerpedia Galactica

Triangulum gets it's name from it's three brightest stars. Big deal! Take any three stars. They form a triangle. OK, ok, so you could probably pick three stars that are equidistant from each other on a great circle line around the Celestial Sphere. Not only would they form a line, but you'd only be able to see at most two of the three on any one night. Most small groups of three stars form a triangle. Geez.

On the dim side, this small constellation does have M33.
