Quadrilateral angles                                        paper quadrilaterals,
                                                                         scissors



      Zena  named the four angles of this
      quadrilateral a,  b,  c and  d.



      The she tore it  into four pieces
      around  its corners.







      She found that the angles fitted together
      in  a  full turn without gaps or overlaps.

      She glued them down to show her teacher.

















             Experiment with different quadrilaterals
             to find out if what Zena thinks is true.

























             Afterwards, write down what you  discover.
