Question

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

Answer 1

If two angles of the triangle are obtuse in a triangle, then the sum of interior angle of the triangle would become more than ${180}^{\circ }$
And also, all the angles in the triangle cannnot be more than ${60}^{\circ }$ because of the same reason.

$\therefore$ (i), (iii) are wrong because the sum of all three angles should be ${180}^{\circ }$.
