A method for finding the area of any polygon when the coordinates of its vertices are known. In this python program. we have defined a function triangle area() that takes coordinates of the triangle arguments.

#### For Cartesian Coordinate Systems The.

Lets find out the area of a. (i) plot the points in a rough diagram. Note that a triangle forms a plane it is desirable to use two dimensional coordinate system.

#### We Have A Formula Which Can Be Directly Used On The Vertices Of Triangle To Find Its Area.

It uses herons formula and trigonometric functions to calculate a given triangles area and other properties. This formula allows you to calculate the area of a triangle when you know the coordinates of all three vertices. From the coordinates of the vertices. calculate the lengths of three sides.

#### Using Information About The Sides And Angles Of A Triangle. It Is Possible To Calculate The Area Without Knowing The Height.

Numerous other formulas exist. however. for finding the area of a triangle. depending on what information you know. When the figure has a known area formula. the area can also be found from the coordinates. The matrix method for computing area is described below.

#### The First Number Tells The X Value While The Second Number Is The Y Value.

Now area of the triangle is 1/2vectorabxvectorac=1/2 (x1i)x (x2i+y2j)=1/2x1y2k. If coordinates of c in the chosen coordinate system are x2.y2 then vector ac= (x2.y2). Area (∆abc) = ½ bc sin a area (∆abc) = ½ ab sin c

#### This Calculator Determines The Area Of A Triangle Using Its Vertex Coordinates In The Cartesian Coordinate System.

Connect the dots and identify the figure. By counting the grid lines we see that the sides = 3. The formula for the area of a triangle is (1/2) × base × altitude.
