This is the second semester of a course that formalizes what students learned about geometry in the middle grades with a focus on reasoning and making mathematical arguments. Mathematical reasoning is introduced with a study of triangle congruency, including exposure to formal proofs and geometric constructions. Then students extend what they have learned to other essential triangle concepts, including similarity, right-triangle trigonometry, and the laws of sines and cosines. Moving on to other shapes, students justify and derive various formulas for circumference, area, and volume, as well as cross-sections of solids and rotations of two-dimensional objects. Students then make important connections between geometry and algebra, including special triangles, slopes of parallel and perpendicular lines, and parabolas in the coordinate plane, before delving into an in-depth investigation of the geometry of circles. The course closes with a study of set theory and probability, as students apply theoretical and experimental probability to make decisions informed by data analysis.

How To Purchase This Course
Districts wishing to purchase this course should contact the course provider directly (see contact information above) and reference the contract in the "attachments" portion of the page linked here. If you are purchasing an Instructor Embedded course, please note that online instructors need not be certified in the state of Oklahoma. They must be certified to teach the content in at least one state or teach the subject at a college or university. To enroll a student in the course, you will need to obtain from the course provider (a) the instructor’s name; (b) the state through which the instructor is certified, and (c) the instructor’s certification number. If the instructor is employed to teach the subject at a college or university, you will need to obtain that institution’s iPEDS number. This information will be recorded in the SIS when you enroll a student in the course. When enrolling a student in a Content Only course, you must indicate in the SIS the name of the person monitoring the course.
