Chapter 9 Section 1 Math 112 B 02/17/2016 Geometry: - Lines - Surfaces - Angles - Solids Based on 4 things: 1. Undefined terms: point, line, plane 2. Defined terms: definitions; might use undefined terms to define other things 3. Axioms: assume to be true without proving them 4. Theorems: things we prove using undefined terms, definitions, axioms, and other theorems that have been proved 1) What are some ral-world items that could use models for points, lines, planes When using these items, what would you need to clarify or emphasize for students - Points: a dot; in math, points have NO size
