This document provides guidance on solving problems using polygons. It reminds the reader about interior angle measurements of quadrilaterals and triangles, how to find interior angles of any polygon, perimeter and area formulas, relationships between opposite angles in rhombi and parallelograms, properties of regular polygons, and properties of equilateral and isosceles triangles. It also outlines the problem solving process of reading the problem, writing an answer statement, drawing a diagram, filling in known information, finding the answer which may be multistep, and working on sample problems with a partner to share information.
