contents In this paper, first we introduce the notion of reflections on quadratic Rota-Baxter Lie algebras of weight $λ$, and show that they give rise to solutions of the classical reflection equation for the corresponding triangular Lie bialgebra ($λ=0$) and factorizable Lie bialgebra ($λ\neq0$). Then we study reflections on relative Rota-Baxter Lie algebras, and also show that they give rise to solutions of the classical reflection equation for certain Lie bialgebras determined by the relative Rota-Baxter operators. In particular, involutive automorphisms on pre-Lie algebras and post-Lie algebras naturally lead to reflections on the induced relative Rota-Baxter Lie algebras. Finally, we derive Poisson Lie groups and Poisson homogeneous spaces from quadratic Rota-Baxter Lie algebras and relative Rota-Baxter Lie algebras.
