Translations

In this type of transformation, you are simply moving all of the x-coordinates by the same amount AND/OR moving the y-coordinate by the same amount:

  • Point A at location (3, 3) is moved to the right one space:
    • A' would now be at (4, 3)

Reflecting Shapes

A rotation is a transformation where each vertices in a figure is reflected across a given line. Keep in mind that:

      • x-axis has an equation of y = 0
      • y-axis has an equation of x = 0

Rotations

A rotation is another transformation where each vertices in a figure is rotated a given number of degrees around a specific point on the cartesian plane.
