  5. rectangle Here are some special polygons. square A rectangle is a square which the 4 sides are not the same. A square has 4 sides and angles that are the same.

  6. Rhombus parallelograms A rhombus is a square tilted. That means that all the sides are the same but the angles are not the same. A parallelogram is a rectangle tilted. That means that 2 sides are the same and the other 2 are the same but they all have different angles.Opposite sides are parallel.

  7. Trapezoid Dart A dart is a 4 sided figure in the shape of a arrowhead. A 4 sided figure with a set of parallel bases.

  9. There are many types of polygons The way you find out the type of a polygon is by counting the number of sides A 3 sided polygon is called a triangle

  10. A 4 sided polygon is called a quadrilateral

  11. A 5 sided polygon is called a pentagon

  12. A 6 sided polygon is called a hexagon A 7 sided polygon is called a heptagon

  13. Then there is an octagon which has 8 sides Nonagon = 9 sides Decagon = 10 sides

  14. Here is a review of the polygons

  15. Here are some example questions Name this shape

  16. The answer is a pentagon because this shape has five sides

  17. Or the question could be What is the name of the polygon with 5 sides

  18. The answer is pentagon because a pentagon has 5 sides pentagon
