the input stream.

ClosePath (procedure)
Closes any open path and completes the current shape, if need be, by drawing a line from the last point in
the shape to the starting point. This ensures the shape is closed, thus enabling filling to take place if
specified. Only closed shapes can be filled.
Syntax
closepath()
Argument
None

and second lines (or sides) of the triangle, the fourth line of code closes the triangle shape by implicitly
issuing a moveto command.

lineto(1.5,2.0)
lineto(0.5,2.0)
