Edexcel GCSE Maths Spec B – Modular: Booster C © Pearson Education This document may have been altered from the original. If your original shape and centre of enlargement are drawn on a grid, there is a very easy way of drawing the new shape. x Centre of enlargement Original shape We will enlarge this shape with scale factor 2.

Edexcel GCSE Maths Spec B – Modular: Booster C © Pearson Education This document may have been altered from the original. x Firstly note that all ‘moves’ mentioned from this point are made from the centre of enlargement. If your original shape and centre of enlargement are drawn on a grid, there is a very easy way of drawing the new shape.

Edexcel GCSE Maths Spec B – Modular: Booster C © Pearson Education This document may have been altered from the original. x How do I get to a point on the triangle from the centre of enlargement? 2 across 4 down If your original shape and centre of enlargement are drawn on a grid, there is a very easy way of drawing the new shape.

Edexcel GCSE Maths Spec B – Modular: Booster C © Pearson Education This document may have been altered from the original. x Now multiply these moves by the scale factor... 2 across 4 down...2 in this case If your original shape and centre of enlargement are drawn on a grid, there is a very easy way of drawing the new shape.

Edexcel GCSE Maths Spec B – Modular: Booster C © Pearson Education This document may have been altered from the original. x 2 across becomes 4 across 4 down becomes 8 down x Mark the new point. If your original shape and centre of enlargement are drawn on a grid, there is a very easy way of drawing the new shape.
