 Hello and welcome to the session. My name is Mansi and I am going to help you with the following question. The question says by giving a counter example show that the following statement is not true. The statement is if all the angles of a triangle are equal then the triangle is an obtuse angled triangle. So let us start with a solution to this question. Now in this part this is the given statement to us. Now we see that sum of the angles of a triangle is equal to 180 degree. Now if all the angles of the triangle are equal then each angle will be equal to 180 degree divided by 3 that is equal to 60 degree which is not an obtuse angle and therefore triangle is not obtuse angled. So the counter example is that angles of a triangle is equal to 60 degree each for which the statement P that is this is not true. So this is our answer to the question. I hope that you understood the question and enjoyed the session. Have a good day.
