The negation of the statement "The triangle is an equilateral or isosceles triangle and the triangle is not isosceles and it is right angled" is
- A The triangle is not an equilateral or not an isosceles triangle or it is not an isosceles or it is not right angled
- B The triangle is not an equilateral triangle or not isosceles triangle and it is isosceles or it is not right angled
- C If the triangle is an equilateral triangle or an isosceles triangle then it is an isosceles triangle or not right angled
- D If the triangle is an equilateral triangle or an isosceles triangle then it is not isosceles triangle and it is not right angled
Answer & Solution
Correct Answer
(C) If the triangle is an equilateral triangle or an isosceles triangle then it is an isosceles triangle or not right angled
Step-by-step Solution
Detailed explanation
\(P\): The triangle is equilateral. \(Q\): The triangle is isosceles. \(R\): The triangle is right angled. Given statement: \((P \lor Q) \land (\neg Q \land R)\)
