(7) distinct points में से कोई (3) collinear नहीं हैं। Triangles की संख्या निकालने का formula \(^{7}C_3\) क्यों है?
Among (7) distinct points no (3) are collinear. Why is the number of triangles given by \(^{7}C_3\)?
Explanation opens after your attempt
A. क्योंकि कोई भी (3) points एक unique triangle बनाते हैं और order important नहीं हैBecause any (3) points form one unique triangle and order is not important
Concept
A triangle is determined by the set of vertices, not their order. In exams use combinations for geometric selection.
Why this answer is correct
The correct answer is A. क्योंकि कोई भी (3) points एक unique triangle बनाते हैं और order important नहीं है / Because any (3) points form one unique triangle and order is not important. A triangle is determined by the set of vertices, not their order. In exams use combinations for geometric selection.
Exam Tip
Triangle केवल vertices के set से तय होता है, उनके order से नहीं। परीक्षा में geometric selection में combination लगाएं।
