Final answer:
Relative plagiarism is not a recognized type; instead, direct, paraphrasing, and complete plagiarism are common forms that require ethical attribution to avoid.
Step-by-step explanation:
Among the types of plagiarism mentioned, relative plagiarism is not a recognized type. Commonly discussed forms of plagiarism include direct plagiarism, where another's words are copied verbatim without credit; paraphrasing plagiarism, where another's ideas are rephrased without appropriate attribution; and complete plagiarism, which involves taking someone's entire work and presenting it as one's own. Avoiding plagiarism is essential in academic writing, and it requires ethical attribution of all borrowed ideas, whether through direct quotations, paraphrasing, or summaries. Each of these methods serves a purpose in writing, but it's important to use them correctly, ensuring that you maintain your own voice and give proper credit to the original authors of the material you are using in your work.
