Unit of InstructionUnit 5: Quadrilaterals and Coordinate Geometry
Standard(s) Taught

MAFS.912.G-GPE.2.5:  Prove the slope criteria for parallel and perpendicular lines and use them to solve geometric problems such as finding the equation of a line parallel or perpendicular to a given line that passes through a given point.

Learning Targets and Learning Criteria
  • Students will be able to state that parallel lines have the same slope and that perpendicular lines have the opposite reciprocal slopes.
  • Students will be able to determine if lines are parallel or perpendicular using their slopes.
  • Students will be able to write the equation of parallel and perpendicular lines.
  • Students will 
Classroom Activities


  • Students will take a summative on Quadrilaterals.
  • Students may then work on their IXL N.10 to bring their scores up.


  • Students will take notes on equations of lines and learn how to write an equation in Point-Slope form.
  • We will do some work together on the worksheet on Point-Slope form.


  • We will go over and finish the point-slope worksheet.
  • We will then do some review of Quadrilaterals, specifically on how to prove lines are parallel, perpendicular, bisect each other, etc. to help prepare for retest or the DIA.
Assignments Due
  • Worksheet on Point-Slope form must be completed by Friday, February 1.
