Write the sum of the angles of an obtuse triangle.

Write about the sum of the measures of the angles of a triangle.

If the sum of two angles is equal to an obtuse angle, then which of the following is not possible ?

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

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.

Prove that the statement "If all the the angles of a triangle are equal , then the triangle is an obtuse angled triangle " is false .

By giving a counter example, show that the following statements are not true. If all the angles of a triangle are equal, then the triangle is an obtuse angled triangle.

By giving a counter example, show that the following statements are not true p: If all the angles of a triangle are equal, then the triangle is an obtuse angled triangle
