Overview of Geometry

For the CCSS Geometry course, instructional time should focus on seven critical areas:

  1. apply linear equations and the Pythagorean Theorem to the coordinate plane
  2. establish criteria for congruence of triangles based on rigid motions;
  3. establish criteria for similarity of triangles based on dilations and proportional reasoning;
  4. prove theorems using logical arguments;
  5. informally develop explanations of circumference, area, and volume formulas;
  6. Identify relationships in circles and prove them; and
  7. extend work with probability.
