Yeah, not all isosceles (two sides are congruent/same, one side different) triangles are right. The comment only works if it’s a 45-45-90 isosceles triangle.
Any isoceles right triangle is going to have a hypotenuse \sqrt{2} times whatever the congruent sides are. But a non-right triangle is always a little more complicated to deal with.
