I don't think there is such a thing in Sage right now, but its not
hard to make something like that. For example:
def pline(rt_list):
'''
Returns line segments passing through the given list of points
in polar coordinates.
'''
cart_list = [[x[0]*cos(x[1]),x[0]*sin(x[1])] for x in rt_list]
return line(cart_list)
I'm not sure what a good name for that would be, "pline" is pretty
bad.
