GCSE Maths Practice: pythagoras-theorem

Question 7 of 10

This question tests understanding that Pythagoras' Theorem calculates direct distances.

‹ ›

\( \begin{array}{l}\text{Which problem situation would involve using Pythagoras' Theorem?}\end{array} \)

Choose one option:

\( \text{A straight-line distance between two points} \) \( \text{The perimeter of a hexagon} \) \( \text{The area of a rectangle} \) \( \text{The surface area of a sphere} \)

Use Pythagoras for direct distances, not perimeter or area.

Pythagoras' Theorem provides the method to find the straight-line distance between two points in 2D or 3D space. It does not calculate perimeters, areas, or surface areas. Understanding this ensures accurate problem-solving in geometry, navigation, architecture, and real-world measurement problems. Practising straight-line distance problems using the theorem develops spatial reasoning, algebraic manipulation, and confidence for GCSE exam questions.
