Line up the top and bottom of the eye with the image, draw in a line - solid in the air, dotted behind the mirror, bounce it back to the object. Place arrows pointing away from the object, to the mirror, and then into the eye.
#1
top of the object, parallel to the axis, strikes the mirror, reflects through F
#2
top of the object, passes through C, strikes the mirror, reflects back through C
#3
top of the object, passes through F, strikes the mirror, reflects parallel to the axis
#1
top of the object, parallel to the axis, strikes the mirror, lines up with F, reflects back (dot back reflection to F)
#2
top of the object, aims for C, strikes the mirror, reflects back (dot back reflection to C)
#3
top of the object, aims for F, strikes the mirror, reflects parallel to the axis (dot back parallel reflection)
