Hi;
There is built in funtion in c++ for drawing a rectangle
U should include graphics.h as the header file
and call the function rectangle(int,int,int,int);
It takes four parameter as x1,y1,x2,y2 as the coordinates
For the angle U can calculate from the angle that what coordinates u have to give,,,,,,,,.
I hope that the problem is clear but if still there are some problems ask again......

Take the points (1,1), (1,-1), (-1,1) and (-1,-1). Stretch the set to however wide/tall you need, then run all four through
x *= cos(a);
y *= sin(a);
It's the same principle as in the rotated-ellipse problem.
