Question

Which of the following sets could not represent the sides of a triangle? {3, 4, 5} {2, 2, 4} {3, 3, 5}

Answer 1

{2, 2,4} is the correct answer.

Answer 2

Using the Theorem of Pythagoras (a² + b² = c²), let's go through each answer.

{3, 4, 5}

Put in the values:
3² + 4² = 5²
Is it correct? (solve)

Yep! :)

{2, 2, 4}

Put in the values:
2² + 2² = 4²
Is it correct? (solve)

Nope! 2² + 2² = 8. And 4² = 16.

The answer is {2, 2, 4} :)
