Hi!

I have this code and getting this problem: undefined reference to 'vtable for Triangle'.

Thanks for your help!

```
#include<iostream>
using namespace std;
class Point
{
public:
float x,y;
Point(){}
Point(float x,float y):x(x),y(y){};
Point operator=(Point &X);
};
Point Point::operator=(Point &X)
{
this->x=X.x;
this->y=X.y;
return *this;
}
class Figure
{
public:
void status();
virtual float area()=0;
virtual float perimeter()=0;
};
void Figure::status()
{
cout << "Area: " << area() << endl;
cout << "Perimeter: " << perimeter() << endl;
}
class Triangle:public Figure
{
private:
Point A,B,C;
public:
Triangle(){};
Triangle(Point& A, Point& B, Point& C){};
float area();
float perimeter();
};
int main()
{
Triangle T;
return 1;
}
```
