Would generics help?

Not sure how else to deal with varying number of Vector2 s returned

I think I will just create static methods for each shape 
c#
public class CoordinateCalculator
{
  static Vector2 CalculateCircleCoords(Vector2 position) => position;

  static (Vector2, Vector2) CalculateRectCoords(Vector2 position)
  {
    // Calc here
    return (Vector2 pMin, Vector2 pMax);
  }
  
  ...
}
c#
public class CoordinateCalculator
{
  static Vector2 CalculateCircleCoords(Vector2 position) => position;

  static (Vector2, Vector2) CalculateRectCoords(Vector2 position)
  {
    // Calc here
    return (Vector2 pMin, Vector2 pMax);
  }
  
  ...
}

I already can just write the code and keep on going, as I said my goal is to apply SOLID principles 🙂

let's consider this is an interview question You get Vector2 position as argument, create classes/interfaces for Shape where each shape takes different number of position arguments Circle -> 1 Square -> 2 Triangle -> 3 MyWeirdShape -> N What classes/interfaces would you create that applies SOLID

so I have 
c#
void Draw(Vector2 position);
c#
void Draw(Vector2 position);
I pass 300x500 for example, find the center, calculate Vectors for the shape

this is not the case though, 
c#
ImGui.AddCircle(Vector2 pos);
ImGui.AddTriangle(Vector2 p1, Vector2 p2, Vector3);
ImGui.AddRect(Vector2 pMin, Vector2 pMax);
c#
ImGui.AddCircle(Vector2 pos);
ImGui.AddTriangle(Vector2 p1, Vector2 p2, Vector3);
ImGui.AddRect(Vector2 pMin, Vector2 pMax);
you see each shape has different position requirements,

so the solution is abstracting the Calculator

sure I can just implement my calculation under Draw implementation but as I said I won't be able to test

I understand, have already thought of the logic and had asked this question. Was responded I need dependency inversion which made/makes sense. I'm trying to practice SOLID so want to implement things correctly.

because Draw returns nothing and I can't create a unit test for it

I'm using IMGui so, for circle I need single Vector2 for square I need pMin pMax 2 Vector2s for triangle I need 3 Vector2s

❔ Serializing related object EF
I have seen some examples where related model is declared as virtual 
public class City {
  ...
  public virtual Coordinates Coordinates { get; set; }
}
public class City {
  ...
  public virtual Coordinates Coordinates { get; set; }
}
What does virtual do in this case? Which one is correct?
