Use the Variable sliders to decide how many sides your shape will have and how many shapes you want within the circle. The program will calculate the # of degrees the shape will need to turn in order to fit all the shapes within the circle. A circle has 360 degrees.
Your shape can have between 3 and 24 sides. You can have between 1 and 360 shapes within the circle design. FYI: # stands for number, not hashtag. Press the Space will give you a version of the project that counts the shapes as they are formed.
