  4. Example 8-3b Vocabulary Translation A transformation in which a figure is slid horizontally, vertically, or both

  5. Lesson 8 Contents Example 1Draw a Translation Example 2Translation in the Coordinate Plane

  6. Copy below on graph paper. Then draw the image of the figure after a translation of 3 units right and 2 units up. Example 8-1a Copy EFG E’ The translation is 3 units right and 2 units up E Note: Do not draw the arrows Begin with E and move it 3 units right then 2 units up G F Label E’ 1/2

  7. Copy below on graph paper. Then draw the image of the figure after a translation of 3 units right and 2 units up. Example 8-1a The translation is 3 units right and 2 units up E’ Note: Do not draw the arrows E Begin with F and move it 3 units right then 2 units up F’ G Label F’ F 1/2

  8. Copy below on graph paper. Then draw the image of the figure after a translation of 3 units right and 2 units up. Example 8-1a The translation is 3 units right and 2 units up E’ Note: Do not draw the arrows G’ E Begin with G and move it 3 units right then 2 units up F’ G Label G’ F 1/2

  9. Copy below on graph paper. Then draw the image of the figure after a translation of 3 units right and 2 units up. Example 8-1a Connect the dots in order E’ G’ E F’ G F Answer: 1/2

  10. Copy below on graph paper. Then draw the image of the figure after a translation of 2 units right and 4 units down. Example 8-1b Answer: 1/2

  11. Example 8-2a Graph ABC with vertices A(–2, 2),B(3, 4),andC(4, 1). Then graph the image of ABC after a translation of 2 units left and 5 units down. Write the coordinates of its vertices. Plot the 3 coordinates B Label A A(-2, 2) A Label B B(3, 4) C C(4, 1) Label C Connect the dots in order that was plotted 2/2

  18. End of Lesson 8 Assignment

  19. Example 8-3a MULTIPLE-CHOICE TEST ITEMPoint S is moved to a new location, S'. Which white shape shows where the shaded figure would be if it was translated in the same way? AA BB C C DD

  20. Example 8-3a Point S is translated 3 units right and 1 unit down. Identify the figure that is a translation of the shaded figure 3 units right and 1 unit down. Figure A: 3 units left and 1 unit up Figure B: 3 units right and 1 unit down Figure C & D: Moved in different directions than S’ so can be eliminated

  21. Example 8-3a AA BB C C DD Figure B: 3 units right and 1 unit down Answer: B
