Enlargements and reductions change how big or small shapes are, but they keep everything looking the same. Let’s break it down:

• Enlargements:

  • This makes shapes bigger.
  • The angles and overall shape stay the same.

• Reductions:

  • This makes shapes smaller.
  • The angles and shape still remain the same.

To make these changes, we use something called a scale factor. For example, if you want to enlarge a shape by a scale factor of $k$, you multiply all the dimensions by $k$.
