Transformations can change how we look at shapes, but they can also have a big impact on their area and perimeter. Let’s break it down:

1. Translation: This means moving a shape without changing its size or area.

   • For example, if a triangle moves 2 units to the right, its area and perimeter stay the same.

2. Rotation: This is when a shape spins around a point.

   • Just like translation, rotation doesn’t change the area or the perimeter of the shape.

3. Reflection: This is like flipping a shape over a line.

   • When you do this, the area and perimeter remain unchanged too.

4. Enlargement: This makes a shape bigger using a scale factor.

   • For example, if you double the sides of a square from 2 units to 4 units:
     • The original area is $2 \times 2 = 4$
     • The enlarged area is $4 \times 4 = 16$
     • The perimeter changes from 8 units to 16 units.

By understanding these transformations, you can learn how to compare and change shapes easily!
