GCSE Secondary Maths Age 13-17 - Geometry & Measures: The Four Transformations - Explained

The video tutorial explains how to enlarge a shape on a squared grid using a scale factor of 1/3, with a focus on plotting vertices and completing the enlargement process. It also covers the criteria for marks allocation and clarifies the concept of a scale factor less than one, emphasizing that it results in a reduction rather than an enlargement.

What is the scale factor used to enlarge shape A?

• 1/3

• 1/2

• 3/4

• 2/3

How many squares does the bottom vertex move from the center after applying the scale factor?

• Two squares

• One square

• Four squares

• Three squares

What is the new position of the top vertex after applying the scale factor?

• Two squares down

• One square down

• Two squares up

• One square up

How many marks are allocated for a fully correct shape in the enlargement task?

• Two marks

• Three marks

• Four marks

• One mark

What happens to a shape when a scale factor less than one is applied?

• It enlarges

• It shrinks

• It rotates

• It remains the same
