- Regular polygons have all sides of equal length and all interior angles of equal measure.
- Irregular polygons have sides of different lengths and/or angles of different measures.
- For the first section, sort shapes: regular polygons are the two hexagons and the square; irregular polygons are the two triangles, the parallelogram, and the trapezoid.
- For the drawing task: on the grid, draw a square (regular quadrilateral) and any quadrilateral that is not a square, rectangle, or rhombus (e.g., a trapezoid or kite) to represent an irregular polygon.
- For the 2D shapes section: the yellow pentagon is regular; the pink trapezoid, orange triangle, green trapezoid, blue irregular pentagon, and red rhombus are all irregular.
Parent Tip: Review the logic above to help your child master the concept of regular and irregular polygons worksheet.
