I just searched left-handed and right-handed on this dictionary and here are the results:
left-handed: [www.cantonese.sheik.co.uk]
right-handed: [www.cantonese.sheik.co.uk]
If you want to say you are left- or right-something, then maybe 用 左/右 ___ 的/嘅. For example, right-legged could possibly be 用右 腿/腳 的/嘅. Just what I think (a possibly oversimplified attempt at an explanation, who knows).
