if each angle of a triangle is less than the sum of the other two show that the triangle is acute angle.?​

Answer» LET ∠A<∠B+∠C. Then, 2∠A<∠A+∠B+∠C⇒2∠A<180 ∘ ⇒∠A<90 ∘ Similarly, we obtain ∠B<90 ∘ and ∠C<90 ∘ => Each angle of the triangle is less than 90° and HENCE it is an acute-angled triangle. Step-by-step explanation:PLEASE MARK ME AS " BRAINLIST"
