Check list:

  1. Revise earlier work on the necessary and sufficient conditions for polygons to be similar.
  2. Prove (accepting results established in earlier grades):
    * that a line drawn parallel to one side of a triangle divides the other two sides proportionally (and the Mid-point Theorem as a special case of this theorem);
    * that equiangular triangles are similar;
    * that triangles with sides in proportion are similar; and
    * the Pythagorean Theorem by similar triangles.
