Triangulation

• Mathematically, triangulation is a method of finding the coordinates and distance of a point using the properties of a triangle
• Given a point and two reference points, measure the angle between the base and the other two sides in a triangle consisting of that point and two reference points.
• This is a method to find the coordinates and distances for the point by measuring the length of the side and performing calculations using the sine laws.
