Chapter 3, Problem 2(choose chapter or problem)
A four-sided closed figure is called a quadrilateral. Use paper and scissors to investigate the midpoints of the sides of a quadrilateral.
a. On a piece of paper, draw a large quadrilateral with all sides of different lengths.
b. Use a compass to construct the midpoints of the four sides of your quadrilateral. Connect the four midpoints with line segments as shown.
c. Label the inner quadrilateral \(\ell\) and the outer triangles \(a\), \(b\), \(c\), and \(d\). Cut out each triangle. Compare the shape and size of the triangles.
d. Assemble all four triangles to cover quadrilateral \(\ell\) completely. Sketch the arrangement on quadrilateral \(\ell\).
