8th grade Math Guide

about rotating quadrilateral ABCD 60° counterclockwise using center B. As you talk, model mathematical language use and highlight the relationship between quadrilateral ABCD , the image (i.e., quadrilateral A’B’C’D’ ), and the steps taken to rotate quadrilateral ABCD . From lesson 12 “Are You Ready for More?”: A polygon has 8 sides: five of length 1, two of length 2, and one of length 3. All sides lie on grid lines. (It may be helpful to use graph paper when working on this problem.)

Extension

1. Find a polygon with these properties. 2. Is there a second polygon, not congruent to your first, with these properties?
