What two pieces of information are needed to perform an enlargement transformation?
Show answer
A scale factor and a centre of enlargement.
In an enlargement, the ? is the fixed point from which all distances are measured and scaled.
Show answer
centre of enlargement
If a shape is enlarged by scale factor 3, how many times longer is each side of the enlarged shape compared to the original?
Show answer
3 times longer. The scale factor directly determines the ratio of corresponding lengths.
Can the centre of enlargement be specified using coordinates?
Show answer
Yes. The centre can be given as a point (like P) or as coordinate pairs such as (4, -3) or the origin.
In an enlargement with scale factor 2, what is the distance from the centre of enlargement to a point on the enlarged shape compared to the corresponding point on the original?
Show answer
Twice as far. Each point on the enlarged shape is 2 times the distance from the centre compared to the corresponding original point.
What coordinate point is commonly used as a centre of enlargement?
Show answer
The origin, (0, 0).
