Pythagorean Theorem

Front

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.

What is the hypotenuse in a right triangle?

Back

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

If a = 3 and b = 4, what is c in the Pythagorean Theorem?

Back

c = 5, because 3² + 4² = 9 + 16 = 25, and √25 = 5.

What is the relationship between the sides of a right triangle?

Back

In a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

If c = 10 and a = 6, what is b?

Back

b = 8, because 10² = 6² + b², so 100 = 36 + b², thus b² = 64 and b = 8.
