So lets learn the concepts of enlargement and reduction. The lengths of the sides of the new shape are double the lengths of the sides of the original shape. Draw ray lines going through point B and point C.Measure the distances of these points from the centre of enlargement, point P. Multiply the distances by the scale factor 3. Remember that the ray lines can be extended as far as needed. These are called ray lines. To use a centre of enlargement we need to draw lines from the centre of enlargement through the vertices of the original shape. If you do, you can calculate the length. If an enlargement has a scale factor of 2, each side of the image is 2 times larger than the sides of the object. There are also enlargement worksheets based on Edexcel, AQA and OCR exam questions, along with further guidance on where to go next if youre still stuck.
