Plagiarism is using someone else's ideas, research, thoughts, words, graphics, tables, etc., either directly or indirectly, without properly acknowledging where the information is from. You plagiarize when you pass off someone else's work as your own by using their exact words or intellectual property (ideas). Whether you are trying to cheat or not, if you don't tell your readers where you found your ideas or words in your paper, you're plagiarizing.
