Name: ____________________________________________________________________ Date: _______________________ Pd: _________ Whitebeard’s Treasure Activity Project Due Date: Monday March 28, 2016 This project is to be completed individually. This project will count as a quiz grade and will demonstrate that you have mastered the information from unit 6 in an additional way. You may use your notes and family tree only! Use your in class time wisely because you will only be provided one day in class to work on the project. It is recommended that you spend Monday completing the graphs and calculations. Then create a final poster (use copy paper, construction paper, powerpoint, etc) to submit for a grade on Tuesday. While you work, consider the following questions: • What is the formula for finding the midpoint of a line segment? • How can you prove these special characteristics? • Which of the quadrilaterals are special quadrilaterals? • How many different ways can you prove that you have a special quadrilateral? • What are the characteristics of each special quadrilateral? • What would you have to show/say to convince your math teacher that • What characteristics does you did not guess the name of a quadrilateral QRST appear to quadrilateral?
possess that matches one of the special quadrilaterals? You will submit a poster that shows your solution strategy and final answer. It should include the following information: • Graph of quadrilaterals ABCD and QRST neatly drawn and labeled • Identify the BEST name to describe quadrilateral QRST • Justify your choice with words, symbols, and numerical calculations. Clearly explain how you know that you picked the right special quadrilateral. The calculations and brief explanations should be neatly written on the poster. You must show 2 different ways of knowing which quadrilateral it is for full credit! • A self-­‐assessment of your progress with the poster. • Answers to the extension questions attached. Whitebeard’s Treasure Activity 1 Whitebeard, the notorious pirate of the West Bay, buried treasure on Tiki Island over 200 years ago. Archeologists recently discovered a map showing the location of the treasure. The location has generated quite a bit of media attention, much to the dismay of the archeologists. In order to allow both the media and archeologists to work together, officials have decided to erect two fences around the location, allowing the media access to the site, yet allowing the archeologists room to work. One fence encloses the actual area where the archeologists will work. Another fence surrounds the enclosed dig area. Descriptions of the fencing locations have been provided to the media so they may indicate accessible areas for their employees. Use the given information to draw and label a quadrilateral on graph paper indicating the location of the two fences. 1. Corners of the first fence are located at points A(11,3), B(3,-­‐11), C(-­‐13,-­‐9) and D(-­‐5,9). The media must stay within this fenced area. Connect the points in alphabetical order, and then join point D to Point A. 2. Find and label the midpoints of each segment of quadrilateral ABCD, showing all work. Label the midpoints of the segments as follows: AB has midpoint Q, BC has midpoint R, CD has midpoint S, DA has midpoint T. 3. Connect the four midpoints in alphabetical order to create a new quadrilateral QRST. This quadrilateral represents the fence surrounding the archeological dig site. 4. Quadrilateral ABCD was an ordinary quadrilateral, but QRST is a special one. Determine the special name for quadrilateral QRST, and justify your answer using two different methods. Extension Questions (answer in complete sentences): 1. What two methods did you use to prove what type of of quadrilateral is QRST? 2. What type of quadrilateral is QRST? Back your answer up with proof. Be specific! 3. Did you use any other methods to determine what type of quadrilateral QRST was? Which? 4. Use coordinate geometry to find the midpoint of each of the diagonals of quadrilateral QRST. How does this point help us identify the type of quadrilateral QRST is? 5. How could you use algebra to find the point of intersection of the diagonals of quadrilateral QRST? Show all work.
