 * Congruent Triangle Exploration

Directions for today's lesson: 1. Read Part I of "Something from Nothing" by Steven Strogratz 2. Pick up the Construction Handout from the substitute, a compass and straightedge. 3. Construct an Equilateral Triangle (you are not allowed to use a protractor or ruler) and **prove** it is equilateral by using your construction 4. No talking to anyone else - work on your own!!!! 5. Struggle - the point of this activity is to try to do this on your own. 6. After you've either figured it out or you've struggle for at least 10 minutes read the rest of the article (part II) 7. On your blog, write about your experience trying to construct an equilateral triangle. 8. Respond, in essay form, to the following questions. Please be creative in your blog post. Dont just answer the questions in bullet form put together a story and include all of your detailed thoughts
 * Wednesday, December 5th**
 * What was your initial reaction to this task? Why?
 * What construction were you trying to make?
 * Were you successful?
 * If so, detail what you did to successfully construct an equilateral triangle
 * if not, what prevented you from figuring this out? Detail what you did try
 * According to the article, what is missing in the study of Geometry? Do you agree? Explain.
