1 the law of cosines states where g denotes the angle contained between sides of lengths a and b and opposite the side of length c. Mathematically if you want to determine the distance between two points on a coordinate plane you use the distance formula. For example you might want to find the distance between two points on a line 1d two points in a plane 2d or two points in space 3d.
For the distance formula I used a foldable graphic organizer that shows an example of how to find the distance on a graph and how to find it from just the coordinate points.
