🔑 Key Concepts & Definitions

  • Transformation: A mathematical operation that changes the position, size, or shape of a figure in a coordinate plane.
  • Translation: Moving a figure without rotating or resizing; every point shifts the same distance in the same direction.
  • Rotation: Turning a figure around a fixed point (center of rotation) by a specified angle.
  • Reflection: Flipping a figure over a line (mirror line) to produce a mirror image.
  • Dilation (Scaling): Resizing a figure proportionally from a fixed point (center of dilation) by a scale factor.
  • Isometry: A transformation that preserves distances and angles (e.g., translation, rotation, reflection).
