Focus: Properties and Relationships

The student will describe and identify properties of quadrilaterals. 
Essential Knowledge and Skills
  • Sort and classify polygons as quadrilaterals, parallelograms, rectangles, trapezoids, kites, rhombi, and squares based on their properties. Properties include number of parallel sides, angle measures and number of congruent sides.
  • Identify the sum of the measures of the angles of a quadrilateral as 360°.
Essential Understandings
  • Can a figure belong to more than one subset of quadrilaterals? Any figure that has the attributes of more than one subset of quadrilaterals can belong to more than one subset. For example, rectangles have opposite sides of equal length. Squares have all 4 sides of equal length thereby meeting the attributes of both subsets.
