Which are the side lengths of a right triangle? Check all that apply.

3, 14, and sqrt205

6, 11, and sqrt158

19, 180, and sqrt181

3, 19, and sqrt380

2,9, and sqrt85

3, 14, and sqrt205.

2,9, and sqrt85.

Step-by-step explanation:

Check if they fit the Pythagoras theorem c^2 = a^2 + b^2:

3^2 = 9, 14^2 = 196.

9 + 196 = 205 which is the square of sqrt205.

So this is a right angled triangle.

6^2 + 11^2 = 36 + 121

= 157 Not right-angled.

19^2 + 180^2 = 32761 Not right-angled.

3^2 + 19^2 = 370 Not right-angled.

2^2 + 9^2 = 85, So this is right angled ...
