GCSE Maths Practice: pythagoras-theorem

Question 8 of 10

This question asks for the formula representing Pythagoras' Theorem.

‹ ›

\( \begin{array}{l}\text{Write down the formula for Pythagoras' Theorem.}\end{array} \)

Choose one option:

Hypotenuse² = side1² + side2²; check correct labeling.

Pythagoras' Theorem states that in a right-angled triangle, the square of the hypotenuse equals the sum of the squares of the other two sides: a^2 + b^2 = c^2. This fundamental formula is used for calculating distances, missing sides, and diagonals in right-angled triangles. Understanding and memorising the formula is critical for problem-solving in GCSE geometry and real-world applications such as construction, navigation, and physics. Practising its application ensures accurate calculations and geometric reasoning.
