This is the full problem: The points $A(5,1)$ and $B(-3,6)$ represent one of the equal sides of an isosceles triangle. Determine one of the possible points that would represent the third vertex of the triangle. Provide calculations to support your answer.
This is easy to figure out by graphing out the triangle, though I have no idea how to do it using calculations. Spent $2$ hours still no luck... Thank you in advance for your help.
