Countdown to Exams - Day 43 - Pythagoras' Theorem

Countdown to Exams - Day 43 - Pythagoras' Theorem

Today, we are looking at Pythagoras' Theorem. When you have a right angled triangle and you know two of the lengths, you can use Pythagoras' theorem to work out the third and final side. Important to note that it ONLY works for a right angled triangle. 

Solving questions using Pythagoras' theorem is a three stage process that may alter slightly depending if you need to find the hypotenuse or a shorter side. There will some questions where Pythagoras' theorem will be required as well as trigonometry in more complex questions.

In the video below, Matt explains Pythagoras' theorem and how to use it to find a shorter side or the hypotenuse.
