Virginia SOL 4.MG.5

Classify and describe quadrilaterals using specific properties and attributes.

What students need to be able to do

  • Develop definitions for parallelograms, rectangles, squares, rhombi, and trapezoids through exploration of properties and attributes.
  • Identify and describe points, line segments, angles, and vertices in quadrilaterals.
  • Identify and describe parallel, intersecting, perpendicular, and congruent sides in quadrilaterals.
  • Compare, contrast, and classify quadrilaterals based on parallel sides, perpendicular sides, congruence of sides, and number of right angles.
  • Denote properties of quadrilaterals and identify parallel sides, congruent sides, and right angles using geometric markings.
  • Use symbolic notation to name line segments and angles in quadrilaterals.
