# 4.(i)    By giving a counter example, show that the following statement is not true.    (i) p: If all the angles of a triangle are equal, then the triangle is an obtuse angled triangle.

We know, Sum of all the angles of a triangle = $180^{\circ}$

If all the three angles are equal, then each angle is $60^{\circ}$

But $60^{\circ}$ is not an obtuse angle, and hence none of the angles of the triangle is obtuse.

Hence the triangle is not an obtuse-angled triangle.

Hence the given statement is not true.
