Formula for area of triangle whose vertices are given. You can also drag the origin point at (0,0).
Formula for area of triangle whose vertices are given . Let us consider the triangle given below. The calculator shows a formula and an explanation for each parameter of a triangle. This calculator computes all the main triangle parameters, such as area, medians, altitudes, centroid and incenter. In this article, we will explore the latter method and use it to find the area of a triangle with vertices at (−2,−1), (4,−1), and (6,5). Area of the triangle is a measure of the space covered by the triangle in the two-dimensional plane. Triangle Definition A triangle is a closed figure with 3 angles, 3 sides, and 3 vertices. The area of the triangle ABC is continuously recalculated using the above formula. But if the height of the triangle is not known and its vertices are given, then we can find the area of the triangle using the determinant formula. The area of triangle, the coordinates of whose vertices are A (\ (x_1,y_1\)), B (\ (x_2,y_2\)) and C (\ (x_3,y_3\)) is given by – Area of Triangle ABC = \ (1\over 2\) | [\ (x_1 (y_2-y_3)+x_2 (y_3-y_1)+x_3 (y_1-y_2)\)]| Jul 23, 2025 ยท The above formula is derived by following the cross product of the vertices to get the Area of triangles formed in the polygon. eqbaawkexopemjzcjxhfjemtgutfcijsymhyenemlqnvejalcycwimekoewaouchhvgyhrvnocpox
