This Geometry course can follow any Algebra I program, whether the student has used Saxon Algebra I, Jacob’s Elementary Algebra, or another First year Algebra course. This course presents all the geometrical concepts in a traditional fashion to the high school student. This course will sufficiently prepare the student for questions on the math section of the PSAT, ACT, or SAT standardized tests. Students completing this course as well as a previous Algebra I program will be ready to take the traditional second year of Algebra II. The Kolbe Academy recommended course of study includes continuing with Foerster’s Algebra and Trigonometry upon completion of this Geometry course.

This course is typically done in 9th or 10th grade. Topics include: conditional statements, direct and indirect proofs, Pythagorean theorem, lines and angles, congruence, inequalities, parallel lines, quadrilaterals, transformations, area, similarity, the right triangle, circles, the concurrence theorems, regular polygons and the circle, geometric solids and an intro to trigonometry.

Students taking this course for Kolbe Core (K) credit are expected to complete daily assignments, periodic exams and quizzes.  Kolbe Honors (H) students will go into more depth and cover more material than the Kolbe Core (K) students.

Assignment due-dates and grades are established by the parent.  Optionally, a student may be enrolled in the Self-Paced Plus© grading assistance program to receive grading assistance from a Kolbe Academy faculty or staff member on designated assignments in the course. In this case, parents will still submit final grades to Kolbe for the course, but may choose to incorporate the graded assignments into the student’s overall grade or use the Kolbe-graded assignments to assist in arriving at the student’s final grade.
