Cheat Sheet
- Triangle Fundamentals -
Memorize the Pythagorean theorem a² + b² = c² and special ratios for 45-45-90 (1:1:√2) and 30-60-90 (1:√3:2). According to Khan Academy, these form the backbone of many geometry questions with answers involving right triangles. A quick mnemonic is "Soh Cah Toa" to recall sine, cosine, and tangent ratios for practice geometry questions.
- Circle Theorems & Formulas -
Recall area A=πr² and circumference C=2πr, then apply the inscribed angle theorem: an inscribed angle equals half its central angle. University of Cambridge resources remind us that any angle in a semicircle measures 90°. Jot these down at the start of a geometry quiz to tackle circle problems swiftly.
- Angle Relationships in Parallel Lines -
Know that alternate interior and corresponding angles are equal when lines are parallel, and the sum of interior angles of an n-sided polygon is (n−2)×180°. Math Is Fun highlights drawing a transversal to visualize these relationships clearly. These principles recur frequently in geometry practice questions on angles.
- Area & Perimeter of Polygons -
For a regular polygon, perimeter P=ns (n sides of length s) and area A=¼ns²cot(π/n), or divide the shape into congruent triangles for simpler calculation. MIT OpenCourseWare suggests using radii to split polygons into triangles, making the cotangent form more intuitive. This strategy accelerates your work on any geometry question with answer choices for polygon areas.
- Coordinate Geometry Essentials -
Master the distance formula d=√[(x₂−x)²+(y₂−y)²], slope m=(y₂−y)/(x₂−x), and midpoint ((x+x₂)/2,(y+y₂)/2) from Stewart's UC Berkeley notes. Labeling points before computing reduces errors and streamlines coordinate solutions. These core formulas appear across many practice geometry questions involving the coordinate plane.
