Pythagoras line segments

April 30, 2021 by Simon Deacon Leave a Comment

This video deals with Pythagoras line segment problems, and is aimed at around grade 5 GCSE maths. You’ll need to find a way to create a right angled triangle on the grid and, as always, please do stop the video, try the questions, and compare your solution.

This video deals with slightly different Pythagoras type questions, in the form of calculating a pythagoras line segment. Thse are usually given as coordinates on a graph, and you need to create a right angle triangle.

1. P is the point with coordinates (5, -1).
Q is the point with coordinates (-3, -6)
Calculate the exact length of PQ.

2. X is the point with coordinates (-3, -6).
Y is the point with coordinates (7, -1)
Calculate the exact length of XY.

3. L is the point with coordinates (-9, 10).
M is the point with coordinates (1, -16)
Calculate the length of LM.
Give your answer correct to 3 decimal places.

Here’s a link to the question: Quick Test – Pythagoras line segments

and here’s the answer paper: Quick Test Pythagoras line segments ANSWERS  apologies for the fairly basic pdf – it might be better to watch the video 🙂

These types of questions appear in all the main GCSE exam boards – Edexcel, AQA, OCR and Educas.

Top Tips!

  • Always try to make a sketch of the question
  • Don’t be concerned if it’s a positive or negative gradient – you’re only trying to calculate the length
  • There’s a difference between exact length – usually given in surd form – and a decimal
