Question

Is 2,3,13 set of side lengths forms a right triangle

Answer 1

Side 2,3,13 can become right angled triangle only if square of largest side (13) = square of two small side (2, 3)

: . By Pythagoras theorem,

13^2=2^2+3^2

169=4+9

169=13(which is wrong)

Thus, it is not a right angled triangle
