This document provides a series of math word problems involving transformations. It includes: 1) Five sections with multiple parts assessing skills with translations, reflections, rotations, and enlargements/reductions. Problems include finding coordinates of transformed points and describing transformations. 2) Diagrams of figures on Cartesian planes along with their transformed images under different combinations of transformations. 3) Calculating areas of transformed figures when given the area of the original figure. The document assesses a wide range of skills with geometric transformations, providing practice applying concepts of translations, reflections, rotations, and scale changes to specific word problems and diagrams.
