Fractional Scale Factor Enlargement GCSE Maths
A fractional scale factor enlargement makes a shape smaller while keeping it similar to the original shape.
Example Idea
If a shape is enlarged by scale factor 1/2, every distance from the centre of enlargement is halved.
Exam tip: Measure or count distances from the centre carefully, then multiply by the scale factor.
Common mistake: Students sometimes think enlargement always means making a shape bigger.
