Hi everyone, I read the explanation for this question but I'm not convinced how if the angle ABC is 90, then we can conclude that $$a^2=\frac{1}{a}$$

According to me if the angle ABC is 90, then the triangle becomes isosceles but the sides are $$a^2$$ and $$\frac{2}{a}$$. Because is a triangle rectangle $$(\frac{2}{a})^2 = (a^2)^2 + (a^2)^2$$ ---> $$2 = a^6$$

Can anyone explain why my reasoning is wrong?
Thank you

I'm sorry I tried to look for that thread but couldn't find it. The normal search does not work properly, and I cannot access to the other thread you post. I'll avoid duplicating threads next time. sorry for the inconvenience.
