This is a square which has sides of length 2 in. It is divided into 16 smaller squares each of side 0.5 in. Black construction lines are drawn on the figure as follows. A diagonal line is drawn from the top right-hand corner to the bottom left-hand corner to divide the square into two triangles. The left-hand triangle is divided into two identical triangles by drawing in the diagonal line from the top left-hand corner. The right-hand triangle is divided into five pieces. The midpoints of the sides of the square are joined, forming a small triangle. The midpoint of the long side of this triangle is joined to the midpoint of the first diagonal and to a point quarter of the way (from the top right-hand corner) along this diagonal. The midpoint of the bottom edge of the square is joined to a point quarter of the way from the bottom left-hand corner of the first diagonal.
