This exit slip is designed for geometry students working on finding missing angles. Students are provided with a set of parallel lines and a transversal and a couple of angle measures. With the given information, students must find measures of missing angles using knowledge of parallel lines and transversals and the postulates and theorems that come with them. Students are also asked to critique student work and provide a reason as to why a proof does not receive full credit. The proof addresses the common error students make in not identifying that lines are parallel before using definitions such as alternate interior angles.
