Take questions on test 2. Continue applications of hyperbolic geometry. How to Sew a 2-Holed Cloth Torus.

Save each Sketchpad file (control/click and then download it to the documents folder) and then open it up from Sketchpad and follow the directions:

Sketchpad Shortest Distance Paths

Image of Shortest Distance Paths.

Begin hyperbolic activities.

Begin Euclidean proof presentations.

Go over an application - a proof that the perpendicular bisectors are concurrent

Build a right triangle in Sketchpad and investigate the Pythagorean Theorem.

Go to Applications/Sketchpad/ Samples/Sketches/Geometry/Pythagoras.gsp

Go through Behold Pythagoras!, Puzzled Pythagoras, and then Shear Pythagoras. Click on Contents to get to the other Sketches.

Go through Euclid's proof. Discuss Sibley

Mention the related problem on Project 2 for Friday [Wallace and West Roads to Geometry 1.1 8].

Where is North? Also discuss 8/08 article

Begin the Geometry of the Earth Project. Groups choose their top four problems.

Induction versus deduction. An introduction to minesweeper games as an axiomatic system.

Axiom 1) Each square is a number or a mine.

Axiom 2) A numbered square represents the number of neighboring mines in the blocks immediately above, below, left, right, or diagonally touching.

Examine game 1. History of Euclid's elements and the societal context of philosophy and debate within Greek society. Intro to Geometric Constructions. Begin Euclid's Proposition 1 by hand and by a proof.
