Intuition behind inversions of triangles in circles leading to similar triangles

Was this arithmetic Möbius/Mangoldt function ever used for something?

Prove $\sum_{k\mid n}{\mu(k)d(k)}=(-1)^{\omega{(n)}}$

Proving $P(n) =n^{\phi(n)} \prod\limits_{d \mid n} \left(\frac{d!}{d^d} \right)^{\mu(n/d)}$

How often does the Mertens function vanish?

Equivariant Mobius inversion

Is this Riemann zeta function product equal to the Fourier transform of the von Mangoldt function?
