Answer» Let us consider a triangle ABC with all angles equal. Then, each angle of the triangle is equal to 60. So, ABC is not an obtuse angle triangle. Hence, the statement “p: If all the angles of a triangle are equal, then the triangle is an obtuse angled triangle” is False.

Answer»

Let us consider a triangle ABC with all angles equal.

Then, each angle of the triangle is equal to 60.

So, ABC is not an obtuse angle triangle.

Hence, the statement “p: If all the angles of a triangle are equal, then the triangle is an obtuse angled triangle” is False.
