Galleria Umberto
In
downtown Naples is the public
shopping gallery, Galleria Umberto. The Gallery was built between 1887
and 1891 and was
named after King Umberto I who was the king of Italy
at the time. Below is a view from the center of the
compass rose on the
floor in the center of the gallery. Across the
bottom of the image you can see the four cardinal directions marked on
the floor.
Your task is to construct the compass rose in the GoeGebra applet at
right. Your construction should pass the drag test.
