This document provides a series of warm up exercises related to geometric figures, angles, polygons, and transformations. It includes problems involving classifying and drawing geometric shapes like lines, rays, angles, and polygons. It also has questions about finding missing angle measures, identifying triangle types based on side lengths, solving equations related to angle sums in polygons, finding congruent angles, and performing translations, reflections, and rotations on coordinates.
