Study Notes

Perimeter Formulas

Perimeter of a Square: ( P = 4s ) (s = side length)
Perimeter of a Rectangle: ( P = 2L + 2w ) (L = length, w = width)

Area Formulas

Area of a Square: ( A = s^2 )
Area of a Rectangle: ( A = length \times width ) (A = l x w)
Area of a Circle: ( A = \pi r^2 ) (r = radius)
Area of a Parallelogram: ( A = b h ) (b = base, h = height)
Area of a Triangle: ( A = \frac{1}{2} b h )

Volume Formulas

Volume of a Box: ( V = l \times w \times h )
Volume of a Cylinder: ( V = \pi r^2 h )

Line Formulas and Properties

Slope Formula: Used to determine the slope (m) of a line between two points.
Parallel Lines: Have the same slope (m).
Perpendicular Lines: Have slopes that are negative reciprocals of each other.
Standard Form: The equation of a line can be written in the form ( Ax + By = C ) where A, B, and C are constants.
Slope-Intercept Form: Represents the slope of a line as ( y = mx + b ) where m is the slope and b is the y-intercept.
Point-Slope Form: Used to write the equation of a line given a point and the slope.

Theorems and Special Rules

Pythagorean Theorem: ( a^2 + b^2 = c^2 ) relates the sides of a right triangle (a, b = legs; c = hypotenuse).
Quadratic Formula: Not provided but useful for solving quadratic equations.
Special Product Rules:
- ( (a+b)^2 = a^2 + 2ab + b^2 )
- ( (a-b)^2 = a^2 - 2ab + b^2 )
- ( (a+b)(a-b) = a^2 - b^2 )

Special Factor Rules

Factorization of Squares:
- ( a^2 + 2ab + b^2 = (a+b)^2 )
- ( a^2 - 2ab + b^2 = (a-b)^2 )
- ( a^2 - b^2 = (a+b)(a-b) )
