while classifing triangles on the basis of angles, do we check the largest no. of the three and check if that is smaller, greater or equal to 90 or is there some other way ?

no that is not the way we do ,the way is, we see"is one of the angle of a triangle is above 90 degree ,if yes then obtuse and if it is 90 degree then right angle triangle and if below 90 degree then acute angled triangle.
