Geometry · Area

Rectangle
A = length × width
Triangle
A = ½ × base × height
Circle
A = π × r²
Trapezoid
A = ½ × (b₁ + b₂) × h
Parallelogram
A = base × height

Geometry · Perimeter & Volume

Rectangle perimeter
P = 2(l + w)
Circle circumference
C = 2πr or πd
Rect. prism volume
V = l × w × h
Cylinder volume
V = π × r² × h
Pyramid volume
V = ⅓ × base area × h

Algebra & Lines

Slope between points
m = (y₂ - y₁) / (x₂ - x₁)
Slope-intercept
y = mx + b
Point-slope
y - y₁ = m(x - x₁)
Distance formula
d = √((x₂-x₁)² + (y₂-y₁)²)
Quadratic formula
x = (-b ± √(b² - 4ac)) / 2a
Pythagorean theorem
a² + b² = c²
