    Study Notes

    Surface Area Concepts

    • Total Surface Area: Refers to the complete area covering the exterior of a three-dimensional object, including all faces.
    • Lateral Surface Area: This is the area of the surfaces around a 3D object, excluding the bases, often used in cylinders and prisms.

    Transformations in Geometry

    • Dilation: A geometric transformation that changes the size of a figure, either enlarging or reducing, while keeping its shape proportional.
    • Translation: Moving a geometric figure from one location to another without altering its orientation or size; only the position changes.
    • Reflection: Creates a mirror image of a figure across a specific line, maintaining distance and angles.

    Important Mathematical Principles

    • Pythagorean Theorem: A fundamental equation in geometry for right triangles, stating that the square of the hypotenuse (c) equals the sum of the squares of the other two sides (a² + b² = c²).
    • Product: The result obtained from multiplying two or more numbers together.
