Area of a triangle by determinant (linear algebra) [duplicate]

WebMar 10, 2024 · Remember for a 2 by 2 matrix, the determinant is just this times this minus this times that. And so that's going to be the absolute value of 40 minus 36 which is just the absolute value of 4 … WebLet's evaluate the determinant by expanding along the 3 rd column. Notice that this differs in the area of the triangle only in sign. The reason for this is because of the order the points were chosen in. If the points were chosen to be points 1, 2, and 3 in a different order, then the determinant would change only in sign. raymond ads
