Reference: AQA
A result derived from similarity or area arguments and used to find a missing side in a right-angled triangle, for example a² + b² = c² where c is the hypotenuse.
The formula a² + b² = c² ties the three sides of a right-angled triangle together, with c as the hypotenuse.
For a right-angled triangle with hypotenuse c and legs a and b, a² + b² = c².
The formula a² + b² = c², used with the hypotenuse correctly identified.
