  • What is an image?
    The figure after the transformation.
  • Specifically describe this transformation.
    A rotation
  • How can I get triangle A to triangle C?
    Rotate180 degrees OR reflect over both axes
  • What is a reflection?
    When you flip an image
  • If we reflected this over the x-axis, what would be the new coordinates of point b be?
    (3,-2)
  • How did the blue triangle translate to the red triangle?
    5 units right, 3 units down.
  • How can I move from triangle C to A in just 1 move?
    A reflection
  • What is a pre-image?
    The image before the transformation
  • What is a transformation
    A change in position, direction or size/shape of a figure
  • How can I get from triangle PMT to triangle XYZ?
    Reflect over x-axis then translate 10 units to the left.
  • How did the triangle move?
    Rotated 90 degrees clockwise
  • What would the coordinates of the point (1, 4) be after a translation left 6 units and down 4?
    (-5,0)
  • What transformations must you do to get from figure 1 to figure 3?
    1. Reflection over the y-axis 2. 90 degree rotation counterclockwise
  • What transformation do we use to go from the orange triangle to triangle s?
    A reflection over the y-axis.
  • What kind of transformation brought the red figure to the blue figure?
    A translation
  • Specifically describe this transformation.
    Reflection over the x-axis.
  • What kind of transformation is this?
    Reflection
  • What two directions can you rotate?
    Clockwise and Counterclockwise
  • What is a translation?
    When you slide a figure
  • What kind of transformation brought the red figure to the green figure?
    A reflection
  • What is a rotation?
    When a figure turns or rotates.
