paraphrasing information from a source without referencing the source

copying & pasting Internet information, graphics or media into your work without citing the source

using someone else’s homework or buying papers or research you did not do and turning it in as if you had done the work yourself

not putting quote marks around parts of sources you copy exactly

All of these are plagiarism when a citation for each source you used is not included in your paper, speech, project, etc.

That’s plagiarism.

Say for instance,if you copy from wikipedia and if you didn’t source or acknowledge it,it’s one form of Plagiarism.Since Wikipedia is free,even if you don’t source it it’s not plagiarism.
