About Area of triangle & Collinear points in Determinants

If the points are co-linear, the triangle can’t be formed. So, in case of collinear points, we put area of triangle zero to solve the questions. Similarly, if we have to find a equation of a line through two given points using determinants, we will assume a third general points(x, y) on the line joining the two point, which will make the three points collinear and then apply the formula of area of triangle put it equal to zero.

त्रिभुज का क्षेत्रफल चाहे धनात्मक हो या ऋणात्मक, हम उसे हमेशा धनात्मक ही लेंगे। क्योंकि त्रिभुज का क्षेत्रफल कभी ऋणात्मक नहीं हो सकता। यदि किसी प्रश्न में त्रिभुज का क्षेत्रफल दिया हुआ है तो उस मान तो ऋणात्मक तथा धनात्मक दोनों से हल करेंगे। संरेख बिंदुओं से कोई त्रिभुज नहीं बन सकता है अतः इनसे बनने वाले त्रिभुज का क्षेत्रफल शून्य होगा।
