Geometric Formulas
- Rectangle:
- Perimeter: P = 2l + 2w (where l = length and w = width)
- Area: A = lw
- Square:
- Perimeter: P = 4s (where s = side length)
- Area: A = s²
- Triangle:
- Angle Sum: A + B + C = 180°
- Area: A = ½bh (where b = base and h = height)
- Right Triangle:
- Pythagorean Theorem: a² + b² = c² (where a and b are legs, and c is the hypotenuse)
- Isosceles Triangle:
- Has two equal sides and two equal angles.
- Equilateral Triangle:
- Has three equal sides and three equal angles.
- Circle:
- Circumference: C = 2πr (where r = radius)
- Area: A = πr²
- Rectangular Solid (Cuboid):
- Volume: V = LWH (where L = length, W = width, and H = height)
- Surface Area: S = 2LW + 2LH + 2WH
- Trapezoid:
- Area: A = ½h(b₁ + b₂) (where h = height and b₁ and b₂ are bases)
- Parallelogram:
- Area: A = bh (where b = base and h = height)
- Right Circular Cylinder:
- Volume: V = πr²h (where r = radius and h = height)
- Surface Area: SA = 2πr² + 2πrh
- Sphere:
- Volume: V = 4/3πr³ (where r = radius)
- Surface Area: SA = 4πr²
Other Formulas
- Temperature Conversion:
- Celsius to Fahrenheit: C = 9/5(F - 32)
- Distance, Rate, Time:
- d = rt (where d = distance, r = rate, and t = time)
- Simple Interest:
- I = Prt (where I = interest, P = principal, r = rate, and t = time in years)
- Percent:
- p = br (where p = percent, b = base, and r = rate)
