यदि \(A=\{1,2,3\}\) पर \(R=\{(1,1),(2,2),(3,3),(1,2),(1,3)\}\), तो (R) प्रतिसममित है या नहीं?
If \(R=\{(1,1),(2,2),(3,3),(1,2),(1,3)\}\) on \(A=\{1,2,3\}\), is (R) antisymmetric?
Explanation opens after your attempt
A. हाँYes
Concept
Antisymmetry fails when both directions exist for distinct elements.
Why this answer is correct
Here ((1,2)) is present but ((2,1)) is not, and ((1,3)) is present but ((3,1)) is not.
Exam Tip
So antisymmetry is not violated. चरण 1: प्रतिसममितता तब टूटती है जब अलग तत्वों के दोनों दिशाओं वाले युग्म हों। चरण 2: यहां ((1,2)) है पर ((2,1)) नहीं, और ((1,3)) है पर ((3,1)) नहीं। चरण 3: इसलिए प्रतिसममितता नहीं टूटती।
