Question

Which triangle would be impossible to create?

Answer 1

IM PRETTY SURE IT IS THE OBTUSR EQUILATERAL THE OTHER ONES ARE THE EASIEST TO SOLVE

Answer 2

Obtuse equilateral, because an obtuse triangle needs one angle that is greater than 90 degrees, but in an equilateral triangle all the angles are 60 degrees because all the sides are equal.

If all sides are equal, then all their non-touching angles are equal.

Hope this helps!
