Question

which of the following sets do not form a right triangle?
6,8,10
8,15,17
7,24,26
5,12,13

Answer 1

So you know about pythagoras theorem?

Answer 2

no not really?

Answer 3

Ok the thing is; in any right triangle,

the square of the bigger side equals sum of the squares of smaller sides.

so with 6,8,10,

6^2 + 8^2 = 36 + 64 = 100 which is 10^2.

so u can try with the other 3 and see which one doesn't fulfill this condition.

Answer 4

The third one does not have a right angle because 7^2 + 24^2 = 625. Then the square root of 625 is 25.
