(ii) A triangle cannot have more than one obtuse angle i.e.if one angle of a triangle is obtuse then the other two are acute.

Fill in the blanks to make the following statements true: Sum of the angles of a triangle is ............ An exterior angle of a triangle is equal to the two ............ opposite angles. An exterior angle of a triangle is always ............ than either of the interior opposite angles. A triangle cannot have more than ............ right angles. A triangles cannot have more than ............ obtuse angles.

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

Theorem 5.1 : Two distinct lines cannot have more than one point in common

A right triangle cannot have an obtuse angle.

In a right-angled triangle, the angles other than the right angle are

The bisectors of base angles of a triangle cannot enclose a right angle in any case.
