We have a formula which can be directly used on the vertices of triangle to find its area. if, (x1, x2), (x2, y2) and (x3, y3) are the coordinates of vertices of triangle then. area of triangle =. now, we can easily derive this formula using a small diagram shown below. suppose, we have a. To calculate the area of a triangle with its vertices a(x 1, y 1), b(x 2, y 2), and c(x 3, y 3), follow these simple steps: evaluate the absolute value of the expression |x 1 (y 2 y 3) x 2 (y 3 y 1) x 3 (y 1 y 2)|. divide this value by two to get the area of the triangle. verify this result using our area of a triangle with the coordinates. Learn how to the find the area of a triangle with three given vertices. use this shortcut to get answers in seconds. video by premath. The area of the triangle abc is continuously recalculated using the above formula. you can also drag the origin point at (0,0). where a x and a y are the x and y coordinates of the point a etc this formula allows you to calculate the area of a triangle when you know the coordinates of all three vertices.

To find the area of a triangle, the following steps may be useful. (i) plot the points in a rough diagram. (ii) take the vertices in counter clock wise direction. otherwise the formula gives a negative value. (iii) use the formula given below. and the diagonal products x1y2, x2y3 and x3y1 as shown in the dark arrows. Using the formula, area of a triangle, a = 1 2 × b × h. = 1 2 × 4 (cm) × 3 (cm) = 2 (cm) × 3 (cm) = 6 cm 2. apart from the above formula, we have heron’s formula to calculate the triangle’s area when we know the length of its three sides. also, trigonometric functions are used to find the area when we know two sides and the angle.
