8. An enlargement is when shapes are similar (angles same etc) but the size has altered.
For an enlargement you need three things:
Object/ shape.
Scale Factor - the size of the enlargement (times by distances)
Centre of enlargement - where you measure the distances from.
When working with the centre of enlargement the position of the enlargement matters.
You measure to each corner of your original object going horizontal and vertical.
Then multiple each of those distances by the scale factor.
Start at the centre of enlargement and move each point the mew distances.
Check
Use your ruler to check your enlargement. You do this by lining up similar corners of the shape to the centre of enlargement to see if they are in line.

9. Translations 3 3 right -2 2 left -5 5 down 4 4 up
Translations are where you slide a shape to a new position.
Vectors are used as a measure of distances in a certain direction [ ].
The Vector
The top number goes across the horizontal.
The bottom number goes up and down the vertical.

10. Reflections Reflections are where you flip over an object.
For reflections you need:
An object.
A mirror line.
How to reflect an object
Reflections
1) Choose a point (corner) on the image.
2) You measure directly to the line (quickest way- straight line-perpendicular to mirror line)
3) Then from that point on the mirror line move the same distance/direction
on the other side and mark a point.
4) These points are a reflection of each other.
5) Repeat for another point on the image.
