Which pairing correctly matches mirrors with the lenses that behave like them?

1. The three types of image formed by mirrors are exactly analogous to those formed by lenses. 2. Concave mirrors act like convex lenses, since both are converging and both have a positive focal length. 3. Convex mirrors act like concave lenses, since both are diverging and both have a negative focal length. 4. A flat mirror has an infinite focal length and zero power, so it converges nothing and matches no converging lens. _Source: OpenStax College Physics (CC BY 4.0), Ch 25 "Geometric Optics", section 25.7 Image Formation by Mirrors_
