Which are examples of tertiary sources? Check all that apply.dictionarybiographywork of fictiontextbooknewspaper article

Tertiary sources collect and summarize information from other sources rather than presenting original research or firsthand accounts. A dictionary provides summarized definitions, and a textbook organizes and explains established knowledge, so both are tertiary sources. A biography and a newspaper article are generally secondary sources, while a work of fiction is not a factual research source.
