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.

Parallel Lines is a task developed for geometry students studying properties of parallel and perpendicular lines. Students must be able to construct perpendicular lines, given a set of guidelines, and determine if the lines drawn are parallel. Students must construct an argument by stating a claim and providing evidence and support. The task offers a template for students to create an argument by providing sentence starters for each piece of the argument.
