How is this thin lens equation derived?

@arjunsrinivasan1997 Similar triangles! Those tend to show up a lot in graphics and vision. :')

To arjunsrinivasan1997: The Gaussian thin lens equation was derived from slide 69: https://cs184.eecs.berkeley.edu/sp19/lecture/15-69/cameras-and-lenses

We get the derivation from algebraic manipulation of the two equations of similar triangles.
