Rigid Transformations
 Rigid transformations are changes  in position or orientation of a figure.  Rigid  transformations include:  •translations - slides along a straight line• reflections - flips over a line of reflection• rotations - turns on a fixed point. Translations are best described as: changes in position or orientation of a figureslides along a linear pathflips overs a line of reflectionturns around a fixed point Reflections are best described as: changes in position or orientation of a figureslides along a linear pathflips overs a line of reflectionturns around a fixed point Rotations are best described as: changes in position or orientation of a figureslides along a linear pathflips overs a line of reflectionturns around a fixed point Identify the single transformation shown in the diagram:translationreflectionrotation translationreflectionrotationIdentify the singletransformation shown in the diagram: translationreflectionrotationIdentify the single transformation shown in the diagram: (3,2) → (-3,2)What transformation is the following rule?   (x, y) → (-x, y)RotationReflectionTranslation (-2,3) → (2,-3)What transformation is the following rule?   (x, y) → (-x, -y) ReflectionRotationof 180 degrees over the originTranslation (-1, 1) → (2, -3)What transformation is the following rule?   (x, y) → (x + 3, y - 4) ReflectionRotationTranslation When a shape is reflected across the "x" axis it is an up and down change.  This changes the sign of which coordinate in the ordered pair?the "x" coordinatethe"y" coordinate When a shape is reflected across the "y" axis it is a sideways flip.
