What 2 things do you always need to say to describe an enlargement?

**How many times it is and where the starter is**

What does centre of enlargement mean?

**The centre of enlargement is how big the next one will be**

What is a scale factor?

**A scale factor is a number which scales**

**, or multiplies, some quantity.**

Explain how to work out the scale factor on a grid, and with no grid. Use diagrams you have screenshot from the myimaths lesson.

**With a grid it is more**

**easily because you just look at the small of the bottom and the sides then look at the big one then times it up Eg: 4=8 but when it is small you have draw lines to all of the corners then you measure how big it is to the x and the corner then you double above the corner do it to all then you draw it to the new x you made to make the bigger shape**

What happens to the angle sizes in the corner of the shape when you enlarge it?

**It stays the same**
