  • Identifying trapezoids and parallelograms

    In this lesson you will learn to identify trapezoids and parallelograms by looking at their shared attributes.

  • Sort quadrilaterals by their attributes

    In this lesson you will learn to sort quadrilaterals by grouping them according to their shared attributes.
