Geometry Class Studies Regular Polygons
Kristina O’Connor’s eighth-grade geometry class recently did a Zoom lesson about areas of regular polygons. Students reviewed properties of regular polygons, learned new vocabulary related to the lesson, and discovered new formulas for calculating areas. They reviewed homework questions as a class. O’Connor used the math app, GeoGebra, to teach students about apothem, which is a line drawn from the center of a polygon and perpendicular to its side. “The GeoGebra app we used helped students discover what an apothem is and how useful it can be!” O’Connor said.
