Study Notes
Area and Perimeter Formulas
- Area of a square: A = 2s (s = side length)
- Perimeter of a square: P = 4s (s = side length)
- Area of a rectangle: A = l x w (l = length, w = width)
- Perimeter of a rectangle: P = 2l + 2w
Area and Perimeter of Triangles
- Area of a triangle: A = 1/2bh (b = base, h = height)
- Perimeter of a triangle: P = a + b + c (sum of all sides)
Circular Measurements
- Area of a circle: A = πr² (r = radius, π = Pi)
- Circumference of a circle: C = 2πr
The Pythagorean Theorem
- Fundamental relation in right triangles: a² + b² = c² (where c is the hypotenuse)
Slope Calculation
- Slope formula: m = (y₂ - y₁) / (x₂ - x₁) for two points (x₁, y₁) and (x₂, y₂)
Multiplication Rules
- Negative multiplied by negative equals positive.
- Negative multiplied by positive equals negative.
