If area of triangle by determinant is zero then how are the points?

A. Collinear

Step 1: Identify the concept: this is application of determinant for area. Step 2: If area of triangle formed by three points is zero then the points lie on one straight line. Step 3: Remember area zero means collinear points.

Step 1: concept पहचानें: यह area determinant का application है। Step 2: तीन points से बनने वाले triangle का area zero हो तो वे एक ही straight line पर होते हैं। Step 3: Area zero means collinear points याद रखें।
