Can a triangle have:All angles more than $60^o$?Justify your answer.
To do:
We have to find whether a triangle can have all angles more than $60^o$.
Solution:
We know that,
Sum of the angles in a triangle is $180^o$.
If the triangle has all angles more than $60^o$ then the sum of the angles becomes more than $180^o$ which is not possible.
Therefore, a triangle cannot have all angles more than $60^o$.
