Q30 2023, Geometry: Polygons

ABCD is a square. One point on each of AB and CD; and two distinct points on each of BC and DA are chosen. How many distinct triangles can be drawn using any three points as vertices out of these six points?

ABCD कोई वर्ग है। AB और CD प्रत्येक पर एक बिंदु; और BC और DA प्रत्येक पर दो भिन्न बिंदु चुने जाते हैं । इन छह बिन्दुओं में से किन्हीं तीन बिन्दुओं को शीर्ष ले कर कितने भिन्न त्रिभुज खींचे जा सकते हैं?

Explanation Please wait..

There are no three points in a straight line.

The total number of unique triangles that can be formed using these six points is ⁶C₃.

⁶C₃ = (6 × 5 × 4) / (3 × 2) = 20

Therefore, option (c) is the correct answer.
