For any pair of points, there are six points that could be the third vertex of an isoscelesright triangle.
Let's begin by plotting the given points on a coordinate plane.
Next, we will plot the various points that would create a right triangle when connected to these points. When choosing the third vertex, we need to make sure that one of the angles is 90^(∘) and that two of the sides are the same length.
Now that we found all six points, let's summarize our findings.
