Ruby Koan 151 raising exceptions

Question

I\'m going through the ruby koans, I\'m on 151 and I just hit a brick wall.

Here is the koan:

# You need to write the triangle method in the file \'trian         


        

Answer 1

For the Koan about_triangle_project_2.rb there's no need to change TriangleError class. Insert this code before your triangle algorithm to pass all tests:

if ((a<=0 || b<=0 || c<=0))
    raise TriangleError
end

if ((a+b<=c) || (b+c<=a) || (a+c<=b))
    raise TriangleError
end
