What We Cover in Geometry

Every topic in the Geometry curriculum — taught for genuine understanding, not just test performance.

Unit 1
Points, Lines & Planes
Geometric notation, measuring segments and angles, midpoints, and angle pair relationships.
Unit 2
Proof & Logical Reasoning
Conditional statements, biconditionals, deductive reasoning, and two-column geometric proof.
Unit 3
Parallel & Perpendicular Lines
Transversals, angle pairs, and proving lines parallel.
Unit 4
Triangles & Congruence
Classification, congruence postulates (SSS, SAS, ASA, AAS), CPCTC, and triangle inequalities.
Unit 5
Similarity
Similar polygons, AA similarity, scale factors, and indirect measurement applications.
Unit 6
Right Triangles & Trig
Pythagorean theorem, special right triangles, and SOH-CAH-TOA.
Unit 7
Circles
Central angles, inscribed angles, arc length, sector area, tangents, and chords.
Unit 8
Area, Surface Area & Volume
Area of 2D figures, surface area and volume of 3D solids (prisms, cylinders, pyramids, cones, spheres).
Learning Outcomes

What Your Child Will Be Able to Do

Students develop strong spatial reasoning, logical thinking, and proof skills that support success in all future math courses.

Spatial Reasoning
Visual & Spatial Thinking
The ability to think visually and reason about shapes in 2D and 3D — a lifelong cognitive skill.
Proof Skills
Proof-Writing Mastery
Two-column proof is Geometry's signature skill — builds logical reasoning applicable in every analytical field.
Trig Foundation
Right Triangle Trigonometry
SOH-CAH-TOA introduced in Geometry sets students up for full Trigonometry and Precalculus.
Next Course Ready
Algebra 2 Ready
Students exit with the reasoning and algebraic fluency required for success in Algebra 2.

Student Reviews

What Families Are Saying

Families trust Concept Mastery for expert Geometry support and clear proof-writing instruction.

★★★★★
"My daughter loved math until Geometry proofs stopped her cold. Her CM teacher broke proof-writing into a clear process she could follow every time. She finished with a 91."

★★★★★
"Geometry seemed disconnected from algebra to my son. His CM teacher connected everything — showing how algebraic thinking applies to geometric reasoning. Completely changed his approach."

FAQ

Common Questions About Geometry

Why do students find Geometry harder than Algebra?
Geometry requires spatial reasoning and logical proof — a different cognitive mode than Algebra. We build both skills explicitly and deliberately.
Is coordinate geometry covered?
Yes — coordinate geometry connects Algebra 1 skills to geometric proof throughout our Geometry programme.
Is proof-writing really important?
Yes — it is Geometry's signature skill and builds analytical reasoning applicable in law, philosophy, computer science, and engineering.

Geometry Is More Than Shapes — Build the Reasoning Skills.

Spatial thinking, logical proof, and geometric intuition. Start with a free assessment class and see the difference.
