Transformations and Symmetry

Moving and Flipping Shapes

Transformations change the position or size of a shape but not its basic structure. The main types are:

  • Translation: Sliding a shape to a new position.
  • Rotation: Turning a shape around a point.
  • Reflection: Flipping a shape over a line (mirror image).
  • Dilation: Resizing a shape bigger or smaller, keeping angles the same.

Symmetry

Symmetry means a shape looks the same after a transformation. There are two main types:

  • Line Symmetry: Mirror image across a line.
  • Rotational Symmetry: Shape looks the same after being rotated less than a full circle.

Applications

Transformations and symmetry are everywhere—art, design, robotics, and nature!

Examples

  • A butterfly’s wings show line symmetry.

  • A soccer ball pattern uses rotational symmetry.

In a Nutshell

Transformations move or resize shapes; symmetry makes designs balanced and beautiful.
