among a,b,c., specify the hypotenuse.
that's the tricky part here ;) Check all combinations - too bad 'combvec' doesnt work here
Passes for True, but Failing when I get to false test?? Not sure at the moment what I could be missing.

The 2nd test is incorrect.

function flag = isRightAngled(a,b,c)
x=[a b c];
y=sort(x);
flag = y(1)^2+y(2)^2==y(3)^2;
end

flag = false;
A = (acos((b^2+c^2-a^2)/(2*b*c)))*180/pi;
B = (acos((a^2+c^2-b^2)/(2*a*c)))*180/pi;
C=180-A-B;
D=[A,B,C];
if any(D==90)
flag = true;
end

why is it correct? only because the test case.
a=100, b=20, c=5 will flag true but it not true
