What the paths of three rays which form image after passing through a convex lens?

The three rays that can be used to determine the location of an image formed by a convex lens are:

1. The ray parallel to the principal axis that passes through the focal point after refraction
2. The ray that passes through the center of the lens and continues in the same direction
3. The ray that passes through the focal point before reaching the lens and then emerges parallel to the principal axis.
