Answer

A: "I'm nice." = 나는 착해. (naneun chaghae.)
B: "I don't think so." = 그렇게 생각하지 않아요. (geureohge saenggag haji anayo.)
B: "No, I don't think you're nice." = 아니요. 나는 너가 착하지 않은 것 같아. (aniyo. naneun neoga chaghaji anheun geot gata.)

For other examples just change "chaghada" with other verbs! Hope this helps!
