Determinant method area of triangle
WebThe method used in this research is a case study method with a quantitative descriptive approach. The data analysis technique used is the path analysis method. As for the research population, 11 regional post offices and 205 inspection post offices (Kprk) throughout Indonesia, so that the total population is 216 offices. WebThere are other methods of finding the area of a triangle. For example, we know that the area of a triangle is given by half the length of the base times the height. However, this formula requires us to know these lengths rather than just the coordinates of the vertices.

WebDeterminants of 3 × 3 matrices are called third-order determinants. One method of evaluating third-order determinants is called expansion by minors. ... Determinants could be used to find the area of a triangle if the coordinates of the vertices are known. If a triangles vertices are (a,b), (c,d) and (e,f) the area is ...
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. WebThe area of triangle in determinant form can be evaluated if the vertices of the triangle are given. If we have a triangle ABC with vertices A(x 1, y 1), B(x 2, y 2), and C(x 3, y 3), …
