Area of triangle using determinants
In this Class 12 Mathematics topic from the chapter Determinants, students learn how to find the area of a triangle when the coordinates of its three vertices are given. They use a 3×3 determinant, apply the area formula, and take the absolute value to obtain a positive result. The topic also helps students understand that a zero determinant indicates collinear points, so no triangle is formed, while reinforcing determinant expansion, coordinate substitution, and clear step-by-step algebraic calculation.
