Question

Triangle with vertices formula

Answer 1

Hii friend!!

» Given,the three vertices of a triangle
(x₁,y₁) , (x₂,y₂) and (x₃,y₃)

» Then the area of the triangle is given by the formula,
∆ = $\frac{1}{2}$ | x₁(y₂-y₃) + x₂(y₃-y₁) + x₃(y₁-y₂) |

Hope it helps...!

Answer 2

To find the area of a triangle where you know the x and y coordinates of the three vertices, you'll need to use the coordinate geometry formula: area = the absolute value of Ax(By - Cy) + Bx(Cy - Ay) + Cx(Ay - By) divided by 2. Ax and Ay are the x and y coordinates for the vertex of A.
