Translating the triangle to a different location on the coordinate axes won't change its shape.  

Ignore the translation; concentrate on the three points given.  You might want to sketch the triangle defined by those points.  How would you determine whether this triangle is a right triangle or not?

A right triangle is created by two perpendicular lines. If you graph the triangle and find the slope of each line, then if there are two perpendicular lines, then yes it is a right triangle.
