Unit Test – Friday 12/14

  • 4 types of Transformations
  • Rigid Transformations & Isometry
  • Reflections
    • Over a horizontal line (y = #)
    • Over a vertical line (x = #)
    • Over the line y = x (diagonal line)
    • Over the x-axis
    • Over the y-axis
  • Rotations
    • 90 degrees counterclockwise
    • 90 degrees clockwise
    • 180 degrees
  • Translations
    • Moving on the x-axis
      • Going to the right you add
      • Going to the left you subtract
    • Moving on the y-axis
      • Going up you add
      • Going down you subtract
  • Dilations
    • Multiply your x and y values by the scale factor.  Scale factor is represented with the letter k.
  • You will be expected to know your rules.  They will NOT be given to you and you may NOT use the blue sheet on the test.

Expectations for the Transformation Unit

  • All graphing MUST be done in PENCIL!
  • Use a RULER/STRAIGHT EDGE when drawing lines
  • Once we start Transformations it is your responsibility to MEMORIZE the rules.  They will NOT be given to you on a test or quiz.
  • Look at each day’s lesson when you do your HW, seeing things in color will help!
