Can a triangle have: Two right angles? (ii) Two obtuse angles? Two acute angles (iv) All angles more than `60^0` ? All angles less than `60^0` ? (vi) All angles equal to `60^0`

Can a triangle have two obtuse angles ? Give reason for your answer.

Is it possible to have triangle, in which Two of the angles are right? Two of the angles are obtuse? Two of the angles are acute? Each angle is less than 60^0? Each angle is greater than 60^0? Each angle is equal to 60^0? Give reason in support of your answer in each case.

Which of the following statements are true (T) and which are false (F): Sum of the three angles of a triangle is 180^0 A triangle can have two right angles. All the angles of a triangle can be less than 60^0 All the angles of a triangle can be greater than 60^0 All the angles of a triangle can be equal to 60^0 A triangle can have two obtuse angles. A triangle can have at most one obtuse angles. In one angle of a triangle is obtuse, then it cannot be a right angled triangle. An exterior angle of a triangle is less than either of its interior opposite angles. An exterior angle of a triangle is equal to the sum of the two interior opposite angles. An exterior angle of a triangle is greater than the opposite interior angles
