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.

The circum radius of a right angled triangle is

If the ratio of three sides of a triangle be 3:4:5, then the triangle will be always a right - angled triangle.

If the three angles of one triangle is equal to that of the three angles of another triangle,the triangles are called

True or false: If the ratio of the lengths of three sides of a triangle is 5 : 12 : 13, then the triangle will always be a right angled triangle.

If the angles of a right angled triangle ar in A.P , then the smallest angle is

If the ratio of the lengths of three sides of a triangle is 3:4:5 ,then the triangle will always be a right-angled triangle.

Write True or False If the ratio of three sides of a triangle is 3:4:5, then the traingle is always a right angled triangle.
