3143 Geometry

Field of Study

Geometry is a branch of mathematics that deals with the measurement, properties, and relationships of points, lines, angles, surfaces, and solids.

Material Covered

This course extends the skills and concepts taught in Algebra I through the study of plane and solid figures. Topics include a review of real numbers, segment and angle measurement, angle relationships, logic, proofs, reasoning, parallel and perpendicular lines, right triangles, trigonometry, quadrilaterals, convex polygons, tessellations, circles, constructions, coordinate geometry, area, similarity, and volume.

Student Expectations

Students are expected to work independently and cooperatively on assignments to discuss real-life problems and problem-solving strategies and to present solutions to proposed problems. Students are expected to use a graphing calculator, have access to a scanner or scanning app, and show their work/steps when solving a problem. Students are also expected to use a compass and a protractor to draw constructions in certain modules of the course.  Students are expected to watch the instructional videos provided, follow the instructions, complete the self-check activities as instructed to do so, and attend the live sessions as much as possible. Students are expected to submit their work in the form of a work-check once every three lessons. On this work-check, students are expected to “show their work” in full detail to confirm and demonstrate that they know what they are doing and can show what they have learned prior to taking a major quiz or test.

How does Geometry differ from Algebra I?

Algebra I is fundamental for building mathematical knowledge. Geometry builds on Algebra I, combining skills learned to abstract shapes, angles, solids, and logical processes to solve real-life problems. Geometry requires students to draw, interact, investigate, and discover properties and rules in math instead of just solving equations. Geometry is considered a fundamental course in mathematics, but it is more abstract than Algebra I in that there are more ways to solve a problem using multiple methods/approaches.

Additional Information

The Virginia Department of Education has approved Geometry as a course to satisfy graduation requirements.
