"My son was really able to grasp Geometry concepts in a way my daughter never did in a regular teacher taught class." – Kristie H.

Geometry

This course requires students to think critically and use logic to prove mathematical theorems and principles. Topics covered in this course include logic and reasoning, distance and length, angles, polygons, circles, perimeter, area, the coordinate plane, transformations, trigonometry, volume, surface area, and probability. This course is best taken in between Algebra I and Algebra II. While not a direct successor to Algebra I, Geometry requires that students have a strong foundation of algebraic skills in order to manipulate equations and solve problems that arise in Geometry. By completing Geometry, students become better prepared for Algebra II, improving their problem-solving skills, abstract and critical thinking, spatial awareness, and logical reasoning.
