Lesson details
Key learning points
- The sum of the squares of the two shorter sides equals the square of the longest side
- The longest side is always opposite the right angle
- 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
Keywords
