Pythagorean Theorem Review Quiz

What is the formula to find the length of the hypotenuse in a right-angled triangle?

• a + b = c

• 2a + 2b = c

• a^2 + b^2 = c^2

• a^2 - b^2 = c^2

How can the Pythagorean theorem be used to find the diagonal of a square with side length 6?

• The diagonal of the square with side length 6 can be found using the formula: diagonal = √(6^2 + 6^2) = √(36 + 36) = √72 ≈ 8.49

• diagonal = 6 + 6 = 12

• diagonal = 6 - 6 = 0

• diagonal = 6 x 6 = 36

What is the converse of the Pythagorean theorem?

• If the square of the length of the longest side of a triangle is equal to the sum of the squares of the other two sides, then the triangle is a right-angled triangle.

• The Pythagorean theorem only applies to isosceles triangles

• The Pythagorean theorem only applies to equilateral triangles

• The square of the length of the longest side of a triangle is not equal to the sum of the squares of the other two sides
