Pythagorean Theorem Basics

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 can be expressed as: a² + b² = c².

What is the longest side of a right triangle called?

Back

The longest side of a right triangle is called the hypotenuse.

What type of angle is formed by the legs of a right triangle?

Back

The legs of a right triangle form a right angle.

Front

If one leg of a right triangle measures 16 and the other leg measures 30, what is the length of the hypotenuse?

Back

Using the Pythagorean Theorem: c² = 16² + 30²; c² = 256 + 900; c² = 1156; c = √1156 = 34.

If the hypotenuse of a right triangle is 40 and one leg is 30, what is the length of the other leg?

Back

Using the Pythagorean Theorem: c² = a² + b²; 40² = 30² + b²; 1600 = 900 + b²; b² = 700; b = √700 ≈ 26.46.
