Given: ABC
= angle A + angle B + angle C=180degree (sum of all angles of triangle is 180 degree )
=angle B + angle C < angle A (reversal property of the given inequality differences of unequals subtracted from equal are unequal in the reverse order)
=angle A + angle A>180 degree (adding angle A to both sides )
2angleA >180 degree (1+1=2)
angleA>90 degree (equals divided by equals )
ABC is an obtuse triangle ( it is an angle >90 degree)
