What are the two types of outlines?

1. Topic outline: This type of outline uses short phrases or words to organize main ideas and subtopics in a hierarchical structure. It typically uses Roman numerals, capital letters, Arabic numerals, and lowercase letters to indicate the level of importance of each point.

2. Sentence outline: This type of outline uses complete sentences to outline main ideas and subtopics in a linear format. It provides more detailed information compared to a topic outline and is often used when writing essays or research papers.
