Transformations

• Transformation an operation that maps or moves
  a figure onto a new figure.
• Types of transformations
• - translation slide/shift
• - reflection mirror image
• - rotation turn
• Image the new figure that is produced from a
  transformation
• Preimage the original image before it was
  translated
• Isometry a transformation that preserves length
  and angle measure (creating congruent figures)

4
Translations

• Decide whether the diagram shows a translation.

5
Translations in the coordinate plane

• Describe the translation of the segment

6
Examples

• Find the image of the point after the
  translation (x, y) (x2, y-4)
• 1. (0, 8)
• 2. (-3, 5)
• 3. (4, -6)

7

• Graph the quadrilateral MATH with vertices
• 
  M(-1,2), A(-1,5),
• 
  T(4,6), H(4,2).
• 
  Find the image of
• 
  each vertex after
• 
  the translation
• 
  (x , y) ? (x 3, y 1)
• 
  and graph the
• 
  image.
