I also don't see how the designation is "cumbersome", compared to the alternatives. (I notice there's no similar complaint about the 45-45-90 triangle.) Like it or not, degrees ARE a worldwide de facto standard for angular measure, and far more widely recognized in non-scientific discourse than radians. While arguments could be (and have been) made regarding the arbitrariness of the degree, this sentence comes off as condescending and dismissive, and this hardly seems the place to bring up that sort of thing. The designation 30-60-90 is not only cumbersome, it references the degree, an arbitrary division of angular measure. The description of the 30-60-90 triangle contains the following sentence: dbolton ( talk) 16:52, 24 January 2010 (UTC) Biased language? Could you explain what the error is? Simply removing an image that is an integral part of the article is not helpful. The previous edit removed the 30-60-90 triangle because of "an error". Perhaps alternative classifications are also possible?

Edge based right triangles are more commonly called Heronian right triangles or Pythagorean triangles, isn't it?). I don't think the classification of special right triangles as angle based and edge based is very common (e.g.

The discustion of radians is lacking and a full 360 degree of the radians should be listed, from Pi/2 - 2pi.- 69.238.168.142 ( talk) 23:08, 1 September 2011 (UTC) Classification This should be put under something other than Special Right Trianles "unit circle" would be more apropriate.

Perhaps someone could pump it up some? ROBO 04:04, 6 October 2007 (UTC) There should be more, for example, a simple formula to find the two sides of a 45-45-90 triangle when one knows only the hypotenuse. On such a broad topic, you'd think that there would be more information available than what is in the article. 6 Right triangle whose angles are in a geometric progression.
