Which of the following statements are...

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
