The problem of the week is a regular installment here at the geometry forum.
Each weekend a high-school level geometry problem will be posted, and the
following weekend a summary of solutions and their authors will be posted.

Once a month a harder, project-like problem will be posted as well, and
students will have a month to work on a solution. The first of these
will be posted at the end of December. The team submitting the most
complete solution will receive Geometry Forum tshirts!

Please do not post solutions to the problem of the week; instead mail your
answer along with as detailed a description of your method as
necessary/possible to (replying to this message
will also work). Solutions should be received by midnight Friday so they
can be combined and posted over the weekend.

Please include your name, grade, and school along with your answer.
