How can I use similar triangles to find points on a mirror?

[zoomba91210]

I am looking at a reflection of an object that is on the floor in a plane mirror. If the object is a certain distance away from the mirror, how would I use the properties of similar triangles to calculate the positions of the points on the mirror that each ray (one to top of eye and other to bottom of eye) reflects?

I am not sure which equations to use or how to approach solving this problem.

Thanks!

Draw a vertical line, that can be the side-on view of the mirrored surface. Draw an object at the position you need it to be. Draw a stick man, that can be you looking towards the mirror.
