## anonymous one year ago Which of the following sets could be the sides of a right triangle? A.) {2, 3,√13 } B.) {2, 2, 4} C.) (1, 2, √3}

1. welshfella

check if the square of longest side = sum of squares on the other 2 sides (Pythagoras:- c^2 = a^2 + b^2)

2. welshfella

is (√13)^2 = 2^2 + 3^2 ?

3. anonymous

Idk

The answer is A. Use Pythagorean Theorem: 2^2 + 3^2 = \sqrt{13}^2

5. anonymous

$2^2 + 3^2 + \sqrt{13}^2$
