Can somebody just tell me how to do this? i don't need the answer. just the process of how to get the answer.

One obvious difference is the Sierra constructing a square and Keaton is constructing a Hexagon. From there, we can determine the other differences. Constructing inscribed polygons requires determining the central angle by dividing 360 degrees by a certain whole number. For regular polygons, this number is equal to the number of sides. For squares, the central angle is 360/4 = 90 degrees while for hexagon, the central angle is 360/6 = 60 degrees.
