Given a triangle with sides [tex]a,b,c[/tex], where c is the longest side:
- If [tex]c^2=a^2+b^2[/tex] then the triangle is right
- If [tex]c^2<a^2+b^2[/tex] then the triangle is acute
- If [tex]c^2>a^2+b^2[/tex] then the triangle is obtuse.
Apply this logic to your triples and you'll classifiy all the triangles.
