  1. Symmetry Question (20 points)
  1. If F is a figure, define what is meant by a symmetry of F.

    2.  

     

  2. Describe and list all the symmetries of this figure (imagine the figure extended infinitely to the right and left in the same pattern). Indicate special lines and points for the symmetries in the figure. You may wish to label some points or lines to make this clearer.

 

 

  1. Composition Question (20 points)

 

In the figure below are given points A and B. If R is rotation with center A by 90 degrees and T is translation by AB, tell what the transformation TR is. (This means tell what kind of transformation it is and also the exact location or size of geometrical objects and numbers needed to tell exactly which transformation it is, such as mirror lines, centers, angles, vectors, distances, etc.)

Also, indicate informally but convincingly your reasoning.
