Correct Answer

A. तुल्यता सम्बन्धEquivalence relation

Step 1

Concept

Every triangle is similar to itself, so the relation is reflexive.

Step 2

Why this answer is correct

If the first triangle is similar to the second, the second is similar to the first.

Step 3

Exam Tip

If the first is similar to the second and the second to the third, then the first is similar to the third. चरण 1: हर त्रिभुज स्वयं के समरूप होता है, इसलिए सम्बन्ध स्वतुल्य है। चरण 2: यदि पहला त्रिभुज दूसरे के समरूप है, तो दूसरा भी पहले के समरूप है। चरण 3: यदि पहला दूसरे के और दूसरा तीसरे के समरूप है, तो पहला तीसरे के समरूप होगा।
