Question

Which of the following is true?
(i) A triangle can have two obtuse angles.
(ii) A triangle can have all angles equal to ${60}^o$.
(iii) A triangle can have all angles more than ${60}^o$.

• A. Only (ii)
• B. Only (i)
• C. Only (iii)
• D. All are true

Answer 1

The correct option is A Only (ii)

(i) If a triangle has two obtuse angles, the sum of angles of the triangle will be more than ${180}^{\circ }$
(iii) If a triangle has all the angles greater than ${60}^{\circ }$, the sum of angles of the triangle will be more than ${180}^{\circ }$
Only (ii) is correct because if all the angles are equal, triangle will be an equilateral triangle and sum of all the angles of the triangle will be ${180}^{\circ }$.
