ROTATION
  • A transformation in which a figure is turned about a point.
  • There are two kinds of rotation direction:
    • clockwise
    • counter clockwise


  • And there are 4 kinds of rotation:
    • 90°
    • 180°
    • 270°
    • 360°

  • Translations are totally different from rotations. Translation is to slide a shape, but rotation is to turn.
  • And it is different from reflection too.
  • assignment page 307-308 , numbers 1-33(0dd numbers only)

HOW TO PLOT REFLECTION
This morning we did mental math to review also.. Then we wrote a note about " How to plot reflection"


How to plot a reflection

Step 1: Plot the coordinates of the original image
Step 2: Draw the reflection line (given question)
Step 3: Plot each reflected point an equal distance away from the reflection line
Step 4: Join the new points

Ex. Plot the qua drilateral A (1,0) , B (1,2), C ( 3, 3) , D ( 3,-1) reflect ( ABCD) in the y-axis and label the image A'B'C'D'











Ex. Plot the triangle X (-1,3) , Y ( 0,3) Z (-3,-1) Reflect the figure over the horizontal line that passes through (0,-2) label the image X'Y'Z'
