How to know the triangle is acute or obtuse?

Are there any ways of checking triangle beside checking every angle?

if (a*a+b*b=c*c) or (a*a+c*c=b*b) or (b*b+c*c=a*a) then
              write('Triangle rectangular')
       else
        if (a*a+b*b<c*c) or (a*a+c*c<b*b) or(b*b+c*c<a*a)   then
        write('треугольник тупоугольный')
        else write('Triangle acute-angled');
