Need a comma

Your immediate problem is that you need a comma after the c in the print statement.

But, also, your algorithm is incorrect in two ways:

You can't assume that c is the largest of the three numbers.
The formula a^2 + b^2 = c^2 only applies to right triangles.

The correct algorithm is that the sum of the two smaller sides must be greater than the largest side.

Another issue is that the declaration of the parameters is wrong. As given, only parameter c is type-checked. You want

proc( a :: positive, b :: positive, c :: positive ) ... end proc

Note that this declaration won't allow, say, IsTriange(1,2,Pi), since Pi is not considered numeric; whether you want to allow that is up to you. If you do, you might declare them as type realcons, then inside the procedure convert them to floats with evalf, check that they are positive, then check that the longest is shorter than the sum of the other two.
