Move the slider downwards and describe the isometries or movements in the plane you can see

  • What type of polygon do you get to? Describe the hidden tile or pattern used by Escher as starting point to draw this figure

After returning to the initial position (clicking on the icon from top to right) now slide the green point upwards and ...

  • Describe the different types of isometries that you can see:
  • Can you find any translation? Select one of them and descríbe it explaining which is its translation vector.
  • Can you see any line of symmetry ? Where?
  • And any rotations? Where is their center? What angle do they have?

With the slider in the top position, a new check box will appear  ("Show points"). Check it and try to modify the drawing.
