5 The hyperbolic plane
... Proof: The proof is a corollary of a difficult theorem called the Riemann mapping theorem. Recall that a space is simply-connected if it is connected and every closed path can be shrunk to a point. The Riemann mapping theorem (proved by Poincaré and Koebe) says that every simply-connected Riemann ...

... The summit angles of a certain Saccheri Quadrilateral (You may have to look this up.) has measure of 83. Find the defect of the quadrilateral. Why should the answer of this problem be exactly twice as much as the answer to the previous problem? ...

Lesson 4.1 • Triangle Sum Conjecture
... a. What would fill the space between your two triangles? Construct !, mark it as center, and rotate the interior of the midpoint of BC !ABC 180° about this point. b. What can you say about the three angles that now meet at point C? c. How does this confirm the Triangle Sum Conjecture? 3. Investigate ...

... Now plot the coordinates (3, -1) and (-1, 1). Plot the line on your board. At what point do these two lines intercept? Look at Figure 4 to see what the two lines look like when plotted together. Using a list of your own coordinates, practice plotting lines and finding slopes. ...
