This is a good problem to refresh basic geometry
The checking should include a random Pythagorean triple (given random natural numbers a>b: a^2-b^2, 2ab, and a^2+b^2 form a Pythagorean triple). For the checking right now, a~=2 passes the tests.
Basic triangle math plus if statements. Great example
This reminds me the old good days ... basic geometry as Sreeram Mohan said :)

Good problem

if (a^2+b^2-c^2==0)
flag = true;
else
flag = false;
end
Easy problem.
Can we please block and ban all these fake answers that cheat the webapp into returning success when they haven't actually solved the problem?
What is wrong with this code?
use
if c==sqrt(a^2 + b^2)
flag=true
else
flag=false
Should add tolerance of 10*eps to make this function practical. Otherwise you can have a triangle with a 89.9999999 deg angle and it will say it is not a right triangle. Matlab is a numerical language.
This user (mohamed elbesealy) appears to have gamed the system, with fraudulent "likes" of this unremarkable solution submitted by 'sock-puppet' accounts. —DIV
mmm c is always grater than a and b
