This Parallel and Perpendicular Lines unit (Geometry Unit 3) provides teachers with ready-to-teach materials on parallel and perpendicular lines in high school geometry. With 58 pages of guided notes, homework assignments, two quizzes, a study guide, and a unit test, it covers everything from transversals and angle relationships to parallel line proofs, slope, and writing equations of parallel and perpendicular lines.
This unit contains the following topics:
• Parallel Lines, Parallel Planes, Skew Lines
• Lines and Angle Relationships: Corresponding Angles, Alternate Interior Angles, Alternate Exterior Angles, Consecutive Interior Angles, Consecutive Exterior Angles
• Parallel Lines Cut by a Transversal: Solving for missing angles and using algebra to solve for missing angles.
• Proving Lines are Parallel: Using converses or algebraically.
• Parallel Line Proofs
• Slope Review: Find slope given a graph or two ordered pairs.
•Parallel and Perpendicular Lines: Using the slope formula to prove lines are parallel, perpendicular, or neither.
• Equations of Lines Review: Slope-Intercept Form, Standard Form, Vertical and Horizontal Lines
• Comparing Equations to determine parallel, perpendicular, or neither.
• The Point-Slope Formula: Writing linear equations given a point and slope or two points.
• Writing Parallel or Perpendicular Equations: Write an equation parallel or perpendicular to a given equation, passing through a specific point.
