Prove whether or not, the following set of coordinates form a right triangle. complete your work in the space provided or upload a file that can display math symbols if your work requires it. a = (2, 1), b = (7, 1), c = (2, 4)

This is a right triangle.

AC forms a line parallel with the Y axis.

AB forms a line parallel with the X axis.

The intersection of AC with AB must therefore be perpendicular.
