find the length between each of the three sets of two points

Solved by pluggable solver: Distance between two points in two dimensions

The distance (denoted by d) between two points in two dimensions is given by the following formula:

Thus in our case, the required distance is

For more on this concept, refer to Distance formula.

Now use Pathogrean theorem. If then it is a right triangle
If two side are the same length, then it is isocelese
