Creation of this resource was inspired by a problem posted by Antonio Gutierrez. You can move the 2 LARGE WHITE POINTS anywhere you'd like at any time. Key Questions: 1) How do we know the octagon shown is a regular octagon? Explain. 2) Suppose each side of the octagon has length a. How can we write the length of the purple segment as a function of a? That is, how can we write the length of the purple segment in terms of a? 3) How can we formally prove the phenomenon dynamically illustrated here?
