Intro to Pythagorean Theorem

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: c² = a² + b².

What is the hypotenuse in a right triangle?

Back

The hypotenuse is the longest side of a right triangle, opposite the right angle.

What is the formula to find the hypotenuse?

Back

To find the hypotenuse (c) of a right triangle, use the formula: c = √(a² + b²).

In a right triangle, what are the two shorter sides called?

Back

The two shorter sides of a right triangle are called the legs.

Front

If one leg of a right triangle is 3 and the other leg is 4, what is the length of the hypotenuse?

Back

Using the Pythagorean Theorem: c = √(3² + 4²) = √(9 + 16) = √25 = 5.
