GCSE Maths Practice: transformations

Question 7 of 10

Understand what transformation creates a mirror image.

‹ ›

\( \begin{array}{l}\text{What transformation creates a mirror image across a line?}\end{array} \)

Choose one option:

Draw the line of reflection and flip each point across it.

Reflection is a transformation that flips a shape over a line, producing a mirror image. Each point of the shape moves perpendicularly across the line of reflection, maintaining size, angles, and shape, but reversing orientation. Recognizing reflections is crucial in geometry, symmetry problems, and coordinate transformations. Practice reflecting simple shapes on grids to see the effect clearly and identify preserved properties. Reflection is commonly applied in design, architecture, and pattern recognition.
