question
which segment is opposite to $\angle r$
answer
$\overline{ra}$ $\overline{rh}$ $\overline{ah}$

Explanation:

In a triangle, the side opposite an angle is the side that does not form the angle. For $\angle R$ in triangle $RHA$ (with right angle at $A$), we identify the sides: $\angle R$ is formed by sides $\overline{RA}$ and $\overline{RH}$. So the side opposite $\angle R$ is the one not connected to $R$, which is $\overline{AH}$.

Answer:

$\overline{AH}$
