Learn how to Find the Area of a Triangle when given 3 Vertices. In our main function we call the Area function twice and output the results. If you know the lengths of the three sides of the triangle you can use Herons Formula to find the area of the triangle.

If youre seeing this message it means were having trouble loading external resources on our website. Area 1 2 b h displaystyle text Area frac 1 2 bh formula to find the area. Uses Herons formula and trigonometric functions to calculate area and other properties of a given triangle.

The calculator uses the following solutions steps. From the three pairs of points calculate lengths of sides of the triangle using the Pythagorean theorem. The hypotenuse is the longest side of a right triangle and is opposite the right angle.

You can also use this formula if you know one side length plus the length of the hypotenuse. It does not matter which points are labelled AB or C and it will work with any triangle including those where some or all coordinates are negative. For cartesian coordinate systems the lengths are calculated as follows For triangle on a plane let z coordinate to remain zero.

X 1 y 1 x 2 y 2 and x 3 y 3 The area is given by. Given the coordinates of the three vertices of any triangle the area of the triangle is given by. Observe the following figure carefully.
