Vedclass · Answer

(A) Let $p$ be the statement "The triangle is an equilateral triangle".Let $q$ be the statement "The triangle is an isosceles triangle".Let $r$ be the statement "The triangle is right angled".The given statement is $(p \lor q) \land (
eg q \land r)$.We need to find the negation: $
eg((p \lor q) \land (
eg q \land r))$.Using De Morgan's Law,$
eg(A \land B) = 
eg A \lor 
eg B$,we get:$
eg(p \lor q) \lor 
eg(
eg q \land r)$.Applying De Morgan's Law again:$(
eg p \land 
eg q) \lor (q \lor 
eg r)$.This translates to: "The triangle is not equilateral and not isosceles,or the triangle is isosceles or it is not right angled".

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
