Pythagoras' Theorem & Trigonometry

This list supports teaching of perimeter, area and volume in secondary mathematics. It provides investigations, problems and games from NRICH as well as classroom activities on the STEM Learning website that compliment them.




Here are some favourite activities selected by the NRICH team.

  • Tilted Squares  Tilted squares are presented on a dotted grid and the challenge is to calculate the area of the squares.
  • Where to Land A swimmer wishes to get back to their family on the shore. Pythagoras' theorem is used to calculate the optimal combination of swimming and running to determine the quickest time to get back.

These are just a few of the activities on Pythagoras' theorem that you can find on the NRICH curriculum pages.




The activities below, taken from the STEM Learning website, complement the NRICH activities above.
