A triangle has sides of lengths 27, 79, and 84. Is it a right triangle? Explain.

Solution

Solution:

Using pythagoras theorem

In a right triangle

Sum of square of two sides are equal to square of hypotenuse

27² + 79² = 6970

and

84² = 7056

thus

27² + 79² 84²

there it is not a right triangle

Answer: Option (D ) No ; 27² + 79² 84² is correct
