Using these resources together improves preparation.
Essential Geometry Formulas for SAT
Area Formulas
Rectangle = length × width
Square = side²
Triangle = 1/2 × base × height
Circle = πr²
Perimeter and Circumference
Perimeter of rectangle = 2(length + width)
Circumference of circle = 2πr
Volume Formulas
Rectangular prism = length × width × height
Cylinder = πr²h
Sphere = 4/3 πr³
Cone = 1/3 πr²h
Pythagorean Theorem
a² + b² = c²
Used in right triangles.
Essential Trigonometry Formulas
Basic Ratios
sin θ = opposite / hypotenuse
cos θ = adjacent / hypotenuse
tan θ = opposite / adjacent
Important Relationships
sin²θ + cos²θ = 1
tan θ = sin θ / cos θ
Common Angle Values
sin 30° = 1/2
cos 30° = √3/2
tan 45° = 1
Knowing these values saves time.
Key Geometry Concepts You Must Understand
Lines and Angles
Vertical angles are equal
Alternate interior angles are equal
Sum of angles in a triangle = 180°
Circles
Radius and diameter relationships
Central and inscribed angles
Arc length
Triangles
Types of triangles
Similar triangles
Right triangle properties
Understanding concepts is more important than memorization.
