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

Geometry 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, parallel and perpendicular lines, convex polygons, congruent triangles, circles, constructions, coordinate geometry, area, and volume of solids.

Student Expectations

Students are expected to work independently and cooperatively on assignments to discuss real-life problems, 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 will be expected to show their work/steps when solving a problem.

How does Geometry differ from Algebra 1?

Algebra 1 is fundamental for building mathematical knowledge. Geometry builds on Algebra 1 combining skills learned to abstract shapes, angles, solids, and logical processes to solve more 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 to be fundamental course in mathematics, but it is more abstract than Algebra 1 in that there are more ways to solve a problem using multiple methods/approaches.

Additional Information

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