              Introducing Angles in a Quadrilateral

              Students are introduced to angles in a quadrilateral by investigating how they are formed from two triangles.  More able students learn how to prove this property using algebra.
              Differentiated Learning Objectives
              • All students should be able to calculate a missing angle in a scalene quadrilateral.
              • Most students should be able to calculate missing angles using the unique properties of each quadrilateral.
              • Some students should be able to prove the sum of the angles in a quadrilateral.
