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?

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
