What is the Pythagorean Theorem?

Back

The Pythagorean Theorem states that in a right triangle, 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). It is expressed as: c² = a² + b².

If a right triangle has legs of length 3 and 4, what is the length of the hypotenuse?

Back

Using the Pythagorean Theorem: c² = 3² + 4² = 9 + 16 = 25, so c = 5.

What is the formula for finding the length of a side in a right triangle?

Back

The formula is derived from the Pythagorean Theorem: c² = a² + b², where c is the hypotenuse and a and b are the other two sides.

What is the length of the missing side if one side is 30 cm and the hypotenuse is 50 cm?

Back

Using the Pythagorean Theorem: 50² = 30² + b², so b = 40 cm.
