C++ compiler error: “invalid declarator before”

Here's my code. When compiling I get the error **invalid declarator before ‘geometry’** at line 16 and line 48, I am not sure what I am doing wrong. Please advise.

#include <iostream>
#include <memory>
#include <vector>
using namespace std;
class FactGeometry
{   //Factory class
public:
static std::shared_ptr<FactGeometry>geometry(int choice);
virtual void calcArea()=0;
};

class CalcRectangle:public FactGeometry
{
void calcArea()
{
double ll,bb,Area;
std::cout<<"\nEnter the length = ";
std::cin>>ll;
std::cout<<"\nEnter the breadth = ";
std::cin>>bb;
Area = ll*bb;
std::cout<<"\nArea = "<<Area;
}
}; //end class

class CalcTraingle:public FactGeometry
{
void calcArea()
{
double bb,hh,Area;
std::cout<<"\nEnter the base = ";
std::cin>>bb;
std::cout<<"\nEnter the height = ";
std::cin>>hh;
Area = 0.5*bb*hh;
std::cout<<"\nArea = "<<Area;
}
};

FactGeometry std::shared_ptr<FactGeometry>geometry(int choice)
{
switch(choice)
{
case 1 : return shared_ptr<FactGeometry>(new CalcRectangle);
break;
case 2 : return shared_ptr<FactGeometry>(new CalcTraingle);
break;
default : std::cout<<"EXIT";
break;
}
} //end class

int main()
{
cout<<"Hello World";
int choice;
std::vector<std::shared_ptr<FactGeometry>> table;
while(1)
{
std::cout<<"1. Rectangle 2. Triangle";
std::cout<<"Enter Choice :";
std::cin>>choice;
if((choice != 1)||(choice != 2))
break;
else
table.push_back(FactGeometry::make_shared<FactGeometry>geometry(choice));
}
for(int i=0;i<table.size();i++)
{
table[i];
}
return 0;
}

I am writing code for Factory Method class but I am getting this error as invalid declarator before ‘geometry’.I am not sure what I am doing wrong
