Extending the Enneagon In Extending the Enneagon, students determine the meaure of an angle formed by extending two sides of an enneagon until they intersect. Elements of this problem are explored in Grade 7, when students “Use facts about supplementary, complementary, vertical, and adjacent angles in a multi- step problem to write and solve simple equations for an unknown angle in a figure.” Combining those concepts with properties of regular polygons is more likely tackled in high school. This task includes:

Regional Ratios In Regional Ratios, students find the ratio of the area of a hexagon to that of an equilateral triangle when the perimeters of the two figures are the same. It might be solved by directly calculating the areas using shape-specific area formulas, calculating the areas using the Pythagorean theorem or the properties of 30-60-90 right triangles, or by dissecting the shapes into smaller equilateral triangles. This task includes:
