I am curious about the following simple problem but I couldn't do any progress on it. I would like to know whether it is possible to prove (with probabilistic proof) that a brownian trajectory contains the vertices of a equilateral triangle. 

## Mathematical Formulation

Let $(W_t)_{t\in[0,1]}$ a standard Wiener process on the interval $[0,1]$. Does it exist $\ell>0$ and $(t_1,t_2,t_3)\in [0,1]^3$ such that:
$$
\begin{cases}
|W_{t_1}-W_{t_2}| = \ell\\
|W_{t_3}-W_{t_2}| = \ell\\
|W_{t_3}-W_{t_1}| = \ell\\
\end{cases}
~~~~\mathrm{?}
$$
