Roads are an example of intersecting lines in the real world.
I need hardly explain where you encounter circles.Ellipses are encountered when you cut a cylindrical object (e.g., a sausage) at an angle. Parabolas are the approximate paths taken by objects thrown into the air (when air resistance is insignificant). Hyperbolas: I may be wrong, but it would seem that these are less common in real life. ALL of the conic sections can be seen when you shine a flashlight onto a level floor (or some other plane), since the light cone is, precisely, a cone.
Scales or balances.
