We notice two symmetric $q$-identities,
which are special cases of the transformations of $_2\phi_1$ series
in Gasper and Rahman's book (Basic Hypergeometric Series, Cambridge 
University Press, 1990, p.~241). In this paper, we give combinatorial
proofs of these two identities and the $q$-binomial theorem by
using conjugation of $2$-modular diagrams.
