Determine If Pythag

-- Determine If a pythag is actually a pythag. I know, this is simple and easy... TO JUSTIFY THAT, I had a very long math assignment assigned by my math teacher about determining if something is a pythag or not.  Making a script would be quicker so uh, here you go have a blast to whoever is reading this.

function is_pythag(a,b,c)
    local aa = a*a
    local bb = b*b
    local cc = c*c
    if aa + bb == cc then
        return {true,aa+bb,cc}
    else
        return {false,aa+bb,cc}
    end
end


g = is_pythag(3,4,5)

if g[1] == true then
    bol = true
else
    bol = false
end

print("Is pythag : "..tostring(bol).."\n"..g[2].." = "..g[3])
