1.0 Credit

This course introduces the student to the deductive method of proof with the use of points, lines, and planes. Solid geometry is integrated with plane geometry to lead the student to consideration of two-and three-dimensional figures and to develop the ability to visualize space relationships. Students who successfully complete this course with a grade of “C” or higher should be prepared for Algebra II.
This course covers the following Geometry concepts:


  • Experiment with transformations in the plane
  • Understand congruence in terms of rigid motions
  • Prove geometric theorems
  • Make geometric constructions


  • Understand similarity in terms of similarity transformations Prove theorems involving similarity
  • Define trigonometric ratios and solve problems involving right triangles
  • Apply trigonometry to general triangles CIRCLES
  • Understand and apply theorems about circles
  • Find arc lengths and areas of sectors of circles


  • Translate between the geometric description and the equation for a conic section
  • Use coordinates to prove simple geometric theorems algebraically


  • Explain volume formulas and use them to solve problems
  • Visualize relationships between two-dimensional and three-dimensional objects


  • Apply geometric concepts in modeling situations
