+118687 I do not know what the answer is but I did find this artical.

Maybe it can help you. OR maybe you can find some other artical or you tube clip that can help you.
Let me know if you work it out. I am interested too.
+26393 We can find an acute triangle with 3 altitude lengths, 1, 2, and h,
if and only if \(h^2\) belongs to interval \((p,q)\).
Find \((p,q)\)
My attempt:
\(\mathbf{p=\ ?}\)
\(\begin{array}{|rcll|} \hline h &=& \dfrac{1\cdot 2}{\sqrt{1^2+2^2}} \\ &=& \dfrac{2}{\sqrt{5}} \\ h^2 &=& \dfrac{4}{5} \\ h^2 &=& 0.8 \\ \mathbf{p} & \mathbf{=}& \mathbf{0.8} \\ \hline \end{array}\)
\(\mathbf{q=\ ?} \)
\(\begin{array}{|rcll|} \hline 1 &=& \dfrac{2\cdot h}{\sqrt{4+h^2}} \\\\ \sqrt{4+h^2} &=& 2h \\ 4+h^2 &=& 4h^2 \\ 3h^2 &=& 4\\ h^2 &=& \dfrac{4}{3} \\ h^2 &=& 1.\overline{3} \\ \mathbf{q} & \mathbf{=}& \mathbf{1.\overline{3}} \\ \hline \end{array}\)
\((p,q) = (0.8,1.\overline{3})\)
+49 Thank you both to heureka and Melody! I read the article, and used heureka's method to find another way to solve the problem.
