Year 10 Pythagoras Worksheets (GCSE) | Printable PDFs
Year 10 Pythagoras worksheets for Year 10 Maths. Students aged 14–15 learn how to use Pythagoras' theorem to calculate missing lengths in right-angled triangles.
Students practise identifying the hypotenuse, finding unknown sides and applying Pythagoras' theorem to solve real-life problems. Pythagoras' theorem states that a² + b² = c², where c is the hypotenuse - the longest side of a right-angled triangle.

Common Questions about Year 10 Pythagoras
What is Pythagoras' theorem?
Pythagoras' theorem is used to find a missing side in a right-angled triangle. It states that the square of the hypotenuse is equal to the sum of the squares of the other two sides.What is the hypotenuse?
The hypotenuse is the longest side of a right-angled triangle. It is always opposite the right angle and is labelled c in Pythagoras' theorem.When do Year 10 students use Pythagoras' theorem?
Year 10 students use Pythagoras' theorem to calculate missing lengths in right-angled triangles and solve real-life problems involving distance, height and geometry.
Year 10 Pythagoras Common Mistakes
Common Mistake 1
A common mistake is choosing the wrong side as the hypotenuse. The hypotenuse is always the longest side and is opposite the right angle.Common Mistake 2
Students often forget to square the shorter sides or forget to find the square root at the end when working out a missing length.Common Mistake 3
Another common mistake is trying to use Pythagoras' theorem on a triangle that is not right-angled, even though the theorem only applies to right-angled triangles.
