GCSE Maths Practice: congruence-and-similarity

Question 10 of 10

This question tests knowledge of the key properties of similar triangles.

‹

\( \begin{array}{l}\text{Which statements are true about similar triangles?}\end{array} \)

Select all correct options:

Check angles are equal and sides proportional. Ignore absolute side lengths.

In similar triangles, corresponding angles are identical and side lengths are in proportion. This allows the shape to remain the same, but overall size may differ. Understanding similarity helps students solve problems involving scale, ratios, and geometric proofs. For example, if one side of a triangle is twice as long as the corresponding side of another similar triangle, all sides scale by the same factor, while angles remain unchanged. Recognizing which properties are preserved under similarity is essential for GCSE geometry, practical applications, and proportional reasoning problems.
