  Study Guide for Stretching & Shrinking Unit Test Essential Learnings: Apply coordinate rules to stretch or shrink shapes and then plot them. Understand ways that stretching or shrinking a figure affects lengths, angle measures, perimeter, and area. Specific Skills: Draw shapes on coordinate grids and use coordinate rules to stretch (x, y), shrink and move the shapes. Determine the way that stretching and shrinking a figure affects lengths, angle measures, perimeters, and areas. Identify similar polygons and use scale factor and side length ratios to prove the similarity between polygons. Calculate the scale factor of two similar shapes and find measures of angles in similar polygons. Apply the relationship of scale factor to perimeter and area. Use the properties of similarity to find distances and heights that you can’t measure. Use specific vocabulary appropriately, use the terms we have learned and discussed in class-specific vocabulary is posted in the classrooms as well...
