The part of the introductory paragraph that states the ideas that will be described in an informative text is typically referred to as the thesis statement. The thesis statement is a clear and concise sentence that provides the main focus or argument of the text. It presents the central idea and gives the reader a preview of the topics or points that will be discussed in the body of the text. This statement usually comes at the end of the introductory paragraph, serving as a roadmap for the rest of the essay or article.
