# Apply the enlargement transformation to familiar two dimensional shapes and explore the properties of the resulting image compared with the original (ACMMG115)

**LO: To use and apply the enlargement transformation to 2-D shapes.**

**Know:**

- the definition of enlargement

**Understand:**

- that objects which are enlarged still retain it’s properties.

**Do:**

- I can use the enlargement transformation to enlarge 2-D shapes.

Enlargement

Enlargement of an object means to make it bigger or larger.

In this case we made the shape 3 times larger. The original triangle had a base of 3 units. The enlargement has a base of 9 units. Since 9 is 3 times larger than 3, we know that this triangle was enlarged by 3x.

All of the properties, such as the angles of the triangles still remain the same after enlargement.
