Mathematics · Geometry · conceptual

Distinguish between regular and irregular polygons based on reasoning about equal sides and equal angles

Sign in to track this

What mastery looks like

  • Classify a set of polygons as regular or irregular
  • Explain that a regular pentagon has 5 equal sides and 5 equal angles
  • Identify that a rectangle is irregular (equal angles but not all equal sides) unless it is a square

Check your understanding

If you show Regular and irregular polygons a stop sign (regular octagon) and a wonky eight-sided shape, can they explain which is regular and which is irregular — and why?
