Answer 3

You use pythagorean theorem and a calculator.
Does
12*12 + 26*26= 28*28?

if we type
12*12 + 26*26=
in the google search window (it does calculations) we get
820

if we type in
28*28=

we get 784. 820 is not 784, so we do not have a right triangle.

on the other hand:
3*3+4*4 = 5*5?
9+16= 25
5*5= 25
so 3,4,5 is a right triangle
