Ollie then dutifully travels to create the requested regular polygon.

 

Their code for Ollie in Tickle App:

After using Scratch to create programs to solve geometry equations for us (too bad we can’t use them on EQAO!) – I challenge you to figure out how to make Mr. Ollie create a regular polygon with 5 sides using the TickleApp. How about 6? 7? 8? 21? Is there a way that the same program (code) could work for all regular polygons if you entered in the number of sides?

Was that too easy? Create an obstacle course for your classmates that requires the use of an angle theorem, pythagorean theorem and/or rate of change when creating a program for Ollie to complete.
