Area of a Triangle
Finding the area of a triangle is straightforward if you know the length of the base and the height of the triangle. But is it possible to find the area of a triangle if you know only the coordinates of its vertices? In this task, youâll find out. Consider ÎABC, whose vertices are A(2, 1), B(3, 3), and C(1, 6); let line segment AC represent the base of the triangle.
Part A
Find the equation of the line passing through B and perpendicular to AC
Part B
Let the point of intersection of Aâ˘C with the line you found in part A be point D. Find the coordinates of point D.
Part C
Use the distance formula to find the length of the base and the height of ÎABC.
Part D
Find the area of ÎABC.
