We know that there are formulas for area of triangle based on the type of the triangle. Area of a triangle. In coordinate geometry we can find the distance between any two points if we know their coordinates and so we can find the lengths of the three sides of the triangle then plug them into Herons Formula to find the area.
Lets find the area of a triangle when the coordinates of the vertices are given to us.
Coordinate Geometry also is known as analytic geometry that describes the link between geometry and algebra using graphs and involving curves and lines. Coordinate Geometry Formula Introduction to Coordinate Geometry. Area of a triangle. The formula for the area of a triangle is 1 2 basealtitude 1 2 base altitude.
