If one angle of a triangle is equal to the sum of the other two angles, then the triangle is

If one angle of a triangle is greater than the sum of the other two, show that the triangle is obtuse angled.

If one angle of a triangle is equal to the sum of the other two angles, then the triangle is (a) an isosceles triangle (b) an obtuse triangle (c) an equilateral triangle (d) a right triangle

If each angle of a triangle is less than the sum of the other two, show that the triangle is acute angled.

If each angle of a triangle is less than the sum of the other two, show that the triangle is acute angled.

If each angle of a triangle is less than the sum of the other two, show that the triangle is acute angled.

If the square of one side of a triangle is equal to the sum of the squares of the other two sides then the triangle is a right triangle with the angle opposite the first sides as right angle.

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
