Elana and Matt have decided to compete in a "challenge" to see whose powers of observation are the strongest in relation to figures drawn on a coordinate plane. You will be acting as the judge (and supreme keeper of the correct answer) during this challenge. Your task is to prepare a proof showing the correct result for each question and to keep track of Elana's and Matt's scores to determine the winner.

Open the files below to begin the challenge. See the "Posts" section for more instructions on how to submit your answers.
