CloudLabs Polygon Apothem vs OctoVocab

In this simulation, you need to build a security key for the screws used in an electronic meter. The screws can range from a triangle to a pentadecagon. It is necessary to measure the sides of the polygon and calculate the area in order to build the key. The simulator recreates a mechanics workshop with a CNC machine, a computer, a vernier caliper, and an electronic meter.
