Each of these can be done in 4 lines of code, and one is import turtle.

Do these challenges in the Python IDLE editor. You will first have to do sheet Writing your own programs using IDLE

In only 4 lines of code (each). Only the 1st need be 4 lines, the others can be 3 lines, as you only have to do import turtle once.

If for each shape we end up where we start, and facing the same way. Then how many times do we turn? What is that in degrees? So for a square we do that in 4 chunks. That is 360/4. What would it be for a triangle, for a hexagon …
What would happen if instead of turning 360°, we turned 2×360°? (in python that is 2*360).

Try some shapes with 5,7,8,9 … sides where the turtle turns 2×360°, or 3×360° or …

How do you need to change 360/n where n is the number of sides.
