Right triangle (Pythagoras) of a Triangle
c² = a² + b²
Where: a = Right triangle (Pythagoras), b = base, c = c
Use the same units for all lengths (e.g. all in cm); areas come out in cm², volumes in cm³.
Solved example
Given: b = 5, c = 10
Find: a (Right triangle (Pythagoras))
- Formula: c² = a² + b²
- Rearranged for a: a = √(-b² + c²)
- Substitute the values: a = √(10² - 5²)
- Rearranged for a: a = -√(-b² + c²)
- Substitute the values: a = -√(10² - 5²)
- Result: a = 8.660254 ; a = -8.660254
Answer: a = 8.660254
