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 :)
Brain clearance
great 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.
