Answer:
# Interactive Drawing
# Shapes
# This is an overview of the shapes that can be drawn on the
# canvas. For full details, please look at the documentation.
# If you are having issues figuring out which shape is drawn
# by which line of code, try commenting some of them out.
# General notes: It is acceptable to use either () or [] when
# listing points. However, be careful that you match
# the number and type of () or [] that you are using. Also,
# polygons and circles have optional parameters that allow
# you to select a fill color.
