Students should be able to classify and sort polygons based on the number of sides and number of vertices. These shapes may include circles and polygons such as a triangle, quadrilateral, rhombus, rectangle, square, pentagon, hexagon, trapezoid, and parallelogram, up to polygons with 12 sides. Students should remember that the attributes of orientation, size, color, and texture do not help identify two-dimensional figures.
Use the polygons shown below to answer the following questions.a) Which polygon has the most sides?
b) Which polygon has 5 fewer vertices than Figure A?
c) Which polygons have the same or more sides than Figure D?
d) Zach said that a square is a quadrilateral. Anna said that a square is a square, so it is not a quadrilateral. Who is right? Explain your thinking?
