                      a.  What can we draw from the following stack of blocks:



                         when   clicked                                 when   clicked

                          move 100       steps                           move           steps

                           turn     90  degrees                          turn         degrees





                          What changes would we need to make to the existing stack of blocks to create a triangle
                        instead of a square?
                      b.   Maya wants to draw a regular octagon (8-sided polygon) in Scratch. What angle
                        should she use for each corner to ensure that the octagon is correctly drawn?
