SECTION 3.1 Relationships Between Lines VOCABULARY Parallel Lines Perpendicular Lines Skew Lines Parallel Planes LEARNING TARGETS: Students will be able to identify parallel, perpendicular, skew lines. Students will be able to identify parallel and perpendicular planes.

Chapter 3 Goals Identify relationships between the angles formed by two lines and a transversal, especially when the two lines are parallel. Use properties of parallel and perpendicular lines to find angle measures. Identify the angle relationships necessary for showing that two lines are parallel. Explore Translations.

Chapter 3 Essential Questions How are properties of geometric figures related to their measurable attributes? How can relationships between geometric figures be verified using the coordinate plane? How are translations in geometry related to functions in algebra?
