Equations of Parallel & Perpendicular Lines (Day 2)

50 Minute Class, Curriculum, Geometry

Learning Goal: Build procedural fluency with determining equations of parallel and perpendicular lines.


Classwork


Standards:

  • Common Core
    • HSG.GPE.B.5 – Prove the slope criteria for parallel and perpendicular lines and use them to solve geometric problems (e.g., find the equation of a line parallel or perpendicular to a given line that passes through a given point).
  • TEKS
    • G.2(B) – derive and use the distance, slope, and midpoint formulas to verify geometric relationships, including congruence of segments and parallelism or perpendicularity of pairs of lines
    • G.2(C) – determine an equation of a line parallel or perpendicular to a given line that passes through a given point
