Geometry & Trig on the SAT

SAT Math · Axiom Academy

Geometry & Trigonometry on the SAT Master the formulas and concepts that appear on ~10% of SAT Math questions. Quick wins if you know the formulas! Why Geometry & Trigonometry Matter Geometry and trigonometry questions on the SAT test your ability to: Calculate areas, perimeters, and volumes using formulas Apply the Pythagorean theorem and special right triangle relationships Understand angle relationships and triangle properties Use trigonometric ratios (sin, cos, tan) to find missing sides and angles Work with circles: equations, arc length, and sector area Solve coordinate geometry problems with distance and midpoint formulas The SAT doesn't ask you to derive formulas—it asks you to apply them. Memorize the key formulas listed in this unit, and you'll solve geometry questions much faster. The Big Picture: Unit 5 Overview Geometry and trigonometry questions cover: Areas & Perimeters: rectangles, triangles, circles, composite shapes 3D Figures: volume and surface area of cylinders, cones, spheres, prisms Angle Relationships: parallel lines, transversals, triangle angle sums Similar & Congruent Triangles: proportions and scale factors Right Triangles: Pythagorean theorem, 30-60-90 and 45-45-90 triangles Trigonometric Ratios: sin, cos, tan and inverse trig functions Circles: equations, arc length, sector area, inscribed angles Coordinate Geometry: distance, midpoint, and coordinate proofs Master the essential formulas and concepts for each geometry/trig topic
