ACT Geometry Practice Cheat Sheet
- Master the Pythagorean Theorem - Embrace the power of right triangles by knowing that a² + b² = c². With this formula, you'll breeze through distance problems and verify right angles like a geometry pro. ACT Math Geometry Guide & Practice
- Understand Special Right Triangles - Spot 45‑45‑90 and 30‑60‑90 triangles in a flash by memorizing their side‑length ratios (x:x:x√2 and x:x√3:2x). This trick saves you precious time on standardized tests. ACT Math Geometry Guide & Practice
- Know the Area Formulas - From triangles to circles, have these in your back pocket: ½·base·height, length·width, and πr². With area rules nailed down, you'll tackle any shape with confidence. Polygons on ACT Math: Strategies & Practice
- Memorize Circumference Formulas - Keep 2πr and πd at your fingertips for anything circular. Whether you're finding perimeters or arc lengths, this quick recall is a lifesaver. ACT Math Circles: Geometry Formulas & Strategies
- Learn the Equation of a Circle - Recognize (x − h)² + (y − k)² = r² at a glance to pinpoint centers and radii. This formula is your golden ticket in coordinate geometry questions. Coordinate Geometry Formulas You Must Know for the ACT
- Parallel Lines & Transversals - Alternate interior and corresponding angles are congruent; consecutive interior angles add to 180°. Master these relationships to slice through line problems effortlessly. ACT Math Formulas
- Sum of Interior Angles in Polygons - Use (n - 2)×180° to find the total degrees inside any n‑sided shape. It's a quick way to tackle weird polygons and angle‑chasing puzzles. Polygons on ACT Math: Strategies & Practice
- Practice the Midpoint Formula - Split the distance perfectly with ((x+x₂)/2, (y+y₂)/2). Whether you're bisecting segments or checking centers, this one's indispensable. Coordinate Geometry Formulas You Must Know for the ACT
- Apply the Distance Formula - √[(x₂ - x)² + (y₂ - y)²] gives you the straight‑line distance between any two points. It's like using a ruler digitally - perfect for coordinate challenges. Coordinate Geometry Formulas You Must Know for the ACT
- Remember the Slope Formula - (y₂ - y)/(x₂ - x) reveals how steep a line climbs or falls. With this in hand, graphing and comparing lines becomes a total breeze. Coordinate Geometry Formulas You Must Know for the ACT
