An equilateral triangle does have, by definition, two equally comparable sides that are, at their base, connected by a third side which is lesser or greater than the lenght of the other sides.
If this case was not the case one would end up with an equilateral triangle, right sided triangle or an isosceles triangle.
The case has to be one or one of the others.
Sorry..I worked in an internationally renown mathematics department for seven years. Groan...I hate the subject!

I am confused??? You say it is an equilateral triangle, and that it has
'long sides' and a wide side??????
