Pythagoras' Theorem: Phone Finding

Australian curriculum number (ACMMG221; ACMMG222)

Students apply Pythagoras’ theorem to explore practical technology that is reliant on mathematical concepts.

This sequence is for students who:

  • have been introduced to Pythagoras’ theorem.
  • are able to complete routine calculations to find the length of the hypotenuse or of one of the short sides.


Lesson 1: Phone Finding

Students apply Pythagoras’ theorem to locate a lost mobile phone, using information about mobile phone towers in their local region. This task develops understandings of the functionality of Pythagoras’ theorem in three dimensions. Students also see the importance of precision when working in real-world contexts.
