GCSE Maths Practice: congruence-and-similarity

Question 4 of 10

This question tests understanding of congruent shapes, an essential concept in geometry.

‹ ›

\( \begin{array}{l}\text{Which statement correctly describes congruent shapes?}\end{array} \)

Choose one option:

Check that all sides and angles are identical. Ignore rotations/reflections. Different size = not congruent.

Congruent shapes have identical sizes and shapes. This means all sides and angles match exactly. Rotation or reflection does not affect congruence, but stretching or resizing would break it. Recognizing congruence is important in geometry problems, proofs, and real-life applications such as engineering or design. Comparing side lengths and angles systematically ensures correct identification. Understanding congruence also helps distinguish it from similarity, where shapes may share the same angles but differ in size. Practicing visual comparisons and using scale measurements strengthens problem-solving skills for GCSE exams.
