Euclid's Elements

We cover Book I of Euclid's elements.  McClure's notes has a section which is a companion to Euclid.

For this part of the course we break ourselves into Eight workgroups.   Each group is responsible for some of the propositions in Euclid, as listed. When we are arrive at your workgroup's proposition, one of the group will be asked to present the proposition to the class from memory. All members of the group present at that time receive the extra credit for the presentation. List of items from Book I

Some slides of Euclid results from class:

• Proposition 22
• Proposition 23
• Proposition 41
• Proposition 42

GEOMETER's SKETCHPAD

GSP is a program designed to mimic  straight edge and compass construction.  GSP can be used to develop intuition and illustrate aspects of a proof, but may not itself stand in place of a proof.  Measurements in GSP are not exact, as you will see through some of the GSP homework assignments.  (Remember that you can get more accurate measurements of  the distance between objects, e.g., points, or a line and a point, by using the calculate function in GSP) .  GSP is installed on all ITAP lab machines, and it is located in the folder: standard software/design tools/Geometer's Sketchpad 4-07, and the icon is GSP 4-07.  It is also available by Software Remote through the ITAP website.
