IS AN EQUILATERAL TRIANGLE CALLED AS A PERFECT TRIANGLE ? IF YES , WHY ?

The term perfect triangle seems to have a few different definitions see for example [1] which defined perfect triangle as triangles with sides of integer length and having numerically equal integer area and perimeter. An equlatrial triangle would never satisfy this definition. --Salix alba (talk) 14:25, 13 April 2007 (UTC)

## Area of Equilateral Triangle

I do not know too much about geometry, so I will post a suggestion for a change. The article states that the area of an equilateral triangle is 1 ${\displaystyle {{\sqrt {3}} \over 4}}$, where 1 is the lenght of a side. I understood it to be s2 ${\displaystyle {{\sqrt {3}} \over 4}}$,where s = side. Of course the given example is 1, so having it squared will make no difference. But given any other number, and it will need to be squared. Is this not a better way of writing the equation? --Mateck 01:33, 2 May 2007 (UTC)

They said it was a duplicate of a formula. --Milesman34 —Preceding undated comment added 13:07, 11 November 2016 (UTC)
