If r and r' are symmetric relations

WebSymmetric relation is a binary relation R defined on a set A for elements a, b ∈ A, we have aRb, that is, (a, b) ∈ R, then we must have bRa, that is, (b, a) ∈ R.

If S and R are both symmetric, then there should be a x, y ∈ S, such that x S y and y S x are true. Also, there should be a x, z ∈ R, such that x S z and z S x, combined them together, we get y S ∘ R z and z S ∘ R y are also true, so S ∘ R should be symmetric. I didn't know if this is the right proof or not.
