What are the two key pieces of information needed to perform an enlargement?
Show answer
The scale factor and the centre of enlargement.
In an enlargement, the ? is the fixed point from which distances are multiplied by the scale factor.
Show answer
centre of enlargement
If a shape is enlarged by scale factor 2, how many times larger are distances from the centre of enlargement?
Show answer
2 times larger. Each point moves to twice its original distance from the centre.
What point can be used as a centre of enlargement that is given by coordinates (0, 0)?
Show answer
The origin.
When performing an enlargement, what happens to a point that lies exactly on the centre of enlargement?
Show answer
It remains in the same position; its distance from the centre is zero, so it does not move.
