What is the relationship between the side lengths of a right triangle?

Back

The square of the length of the hypotenuse (c) is equal to the sum of the squares of the lengths of the other two sides (a and b).

Front

If side a is 3 feet and side b is 4 feet, what is the length of side c?

Back

c = 5 feet (using a² + b² = c²: 3² + 4² = 9 + 16 = 25, so c = √25 = 5).

What is the formula to find the length of one leg if the hypotenuse and the other leg are known?

Back

a = √(c² - b²) or b = √(c² - a²) depending on which leg is unknown.

Front

If a right triangle has legs of 6 feet and 8 feet, what is the length of the hypotenuse?

Back

c = 10 feet (using a² + b² = c²: 6² + 8² = 36 + 64 = 100, so c = √100 = 10).
