Students learn the definition of a polygon as well as the definitions of concave and convex polygons. Students also learn the following polygon classifications: triangle (3 sides) quadrilateral (4 sides) pentagon (5 sides) hexagon (6 sides) heptagon (7 sides) octagon (8 sides) nonagon (9 sides) decagon (10 sides) dodecagon (12 sides).
