GCSE Maths Practice: transformations

Question 4 of 10

Understand the effect of enlarging a shape by scale factor 2.

‹ ›

\( \begin{array}{l}\text{If a shape is enlarged by scale factor 2, how many times larger does it become?}\end{array} \)

Choose one option:

Multiply each side by the scale factor to find new dimensions.

Enlarging a shape by a scale factor multiplies each side length by that factor. A scale factor of 2 doubles all lengths, making the shape twice as large but maintaining angles and overall shape. This is important in similarity, transformations, and geometry problems. Practice applying scale factors to shapes on grid paper or coordinates. Observe how dimensions change while shape properties like angles remain the same. Understanding scale factors is essential for constructing similar figures and solving real-life proportional problems.
