Lesson outcome
I can use Pythagoras' theorem to find the length of one of the shorter sides.
Show transcript
The sum of the squares of the two shorter sides equals the square of the longest side.
The difference between the squares of the longest and known shorter sides is the square of the remaining side.
A calculator can perform these calculations efficiently.
Rounding gives a less accurate answer so there might be times you wish to leave your answer with an operator.
