Yes it can... the side length has nothing to do with the angle measures... I am in 6th grade and i just took the test on this, i got 100%...
An equilateral triangle has 3 sides of equal length (that's what the word equilateral means) and also 3 equal angles, all of which are 60o. A right triangle, by definition, has one right angle of 90o. So if all the angles are 60o then it is not possible to have an angle of 90o, right? COOL!!!!!!!!!I GOT AN A+ on my portfolio thanks to this answer
An obtuse triangle got its name from Egypt. Ob in egyptian is lage tuse is angle
A folded napkin is often folded into a right triangle, but that's all I got. Sorry!
