This worksheet is designed to illuminate common errors students make when proving triangles congruent. There are 13 questions in the style of multiple choice, multiple select, and short answer.
The zipped file folder contains a PDF version as well as an editable Word document if you would like to add/omit/modify any questions.
The format of the questions makes this very easy to grade -- whether you do the grading, students grade themselves or each other, or you adapt it to an online format through Pear Deck, Formative, Google Forms, etc. It is a great way for students to get quick feedback about what they are understanding well vs. where they are falling into some common errors.
