The Total solution for NCERT class 6-12
By giving a counterexample, show that the following statement is not true.p: “If all the angles of a triangle are equal, thenthe triangle is an obtuse angled triangle.”
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 areequal, then the triangle is an obtuse angled triangle” is False.
